Is Your Air Making You Air-itated? AirGradient Knows.

AirGradient make air quality sensors both for indoor and outdoor use. Both currently utilise the same sensors, but the outdoor one is designed to be kept outside (and can be made visible on AirGradient's map, while indoor units are private). The indoor under is the I-9PSL (AirGradient ONE, 9th Generation).

AirGradient Indoor Air Quality Monitor

The units come fully assembled or as kits (slightly cheaper, though construction isn't difficult). The indoor unit came as a kit, and only took a few minutes to put together.

AirGradient box open

The packaging is very simple cardboard, with little wasted.

USB cable and sensor in packaging

The USB A to C cable used right angle plugs, useful for the indoor unit (USB C) but less so for the USB A end, which plugs into a standard USB power supply.

Indoor Sensor box (front)

The indoor unit has the PCB/display already attached to the case.

Inside Indoor unit

Separating the case reveals the PCB and the large Plantower PM1/2.5/10 sensor.

Inside Indoor unit and sensors

The three sensors units need to be (simply) attached to the PCB. There are headers that the sensors just plug on to. The two smaller ones are temperature and relative humidity and TVOC/NOx sensors and the larger the CO2.

Inside Indoor unit with sensors plugged in

It's important to connect the sensors the right way around. The CO2 sensor is obvious while the smaller sensors should face outwards. The Plantower particulate matter detector is pre-installed.

Indoor unit boot screen

Once plugged into power, the system boots does some self tests.

Indoor unit successful boot

Once booted, it shows the firmware version.

Indoor unit LED test

It's possible to press the button and do a LED test.

Indoor unit successful setup

Once everything's done it shows the air quality measurements.

Indoor unit assembled with USB power

The rear of the case showing the USB cable attached and slotted through the case. The feet are also attached (they snap into the airflow slots).

When in setup mode the system enables a local hotspot. Once joined to the hotspot, the device should auto-connect to the hotspot which allows setting the SSID/password of the network to connect to.

Once it connects to the WIFi it will then try and call home and connect to AirGradient's servers. Initially it will show not configured and an account needs to be setup on AirGradient and then using the devices MAC address the device can be added and it will start sending data. The dashboard gives an overview of the air quality, but clicking on the menu item, allows many configuration options.

AirGradient Dashboard

It's possible to access your own data through the AirGradient API or by being pushed out to a MQTT broker, but internal monitor's data won't be pushed to external services such as OpenAQ. Outdoor monitors have a checkbox to allow pushing the data out.

It is possible to connect the unit to services like ESPHome, Prometheus, and openHAB and Apple Home Assistant.

It's all run with a ESP32-C3-MINI (32-bit RISC-V single-core processor, up to 160MHz, 384 KB ROM, 400 KB SRAM, 8 KB SRAM in RTC, 4 MB flash in chip package) and uses a Texas Instruments watchdog timer.

In terms of actual sensors there's the: -

• Particle Sensor Module - Plantower PMS5003 (laser scattering principle). Accuracy Fully Assembled & Tested Model (I-9PSL-DE_asd): Accuracy PM2.5: ±4μg/m3@0~100μg/m3, ±8%@100-500μg/m3. Accuracy Kit Version (I-9PSL-DE_kit): Accuracy PM2.5: ±10μg/m3@0~100μg/m3, ±10%@100-500μg/m3. (PM1 and PM10 are also measured but PM2.5 has the highest accuracy).
• CO2 Sensor Module - SenseAir S8 (NDIR). 400 to 10000ppm. Accuracy: ±40 ppm ±3% of reading at 5 to 30°C, 20- 70%RH (400 - 2000ppm range). SenseAir S88 (NDIR). 0 to 10000ppm. Accuracy: ±40 ppm ±3% of reading at 5 to 30°C, 0- 85% RH (400 - 3000ppm range).
• TVOC/NOx Module - Sensirion SGP41. Accuracy: TVOC <±15 @ 0 to 500 VOC Index (also available in ppb); NOx<±50@0-500NOx Index.
• Temperature and Humidity - Sensirion SHT40. Accuracy: Temperature ±0.2°C @ -40 to + 125°C; Humidity ±2% RH @ 0 - 100% RH.

Though everything works fine, some of the sensors are relatively old now.

THE OLED display shows: -

OLED display

There's a single status LED at the top of the unit and then a row of Pollutant LEDs that indicate air quality.

The status LED shows: -

Status LED

Red: Connection to WI-FI network failed. This may be due to incorrect credentials or unsupported encryption.

Yellow: Connected to WI-FI network but the server can not be reached through the Internet, e.g. blocked by firewall.

Purple: Server is reachable but there is some configuration issue to be fixed on the server side.

The Pollutant LEDs: -

Pollutant LEDs PM2.5

The default settings is to show PM2.5, but this can be changed in the settings to showCO2 (carbon dioxide) settings: -

Pollutant LEDs CO2

Though AirGradient sell units the software, hardware and even the case are available under an open source license.

Though there can be fiddly issues with the install (read the instructions first), it's easy to build and the set-up is easy. WiFi is only 2.4GHz but generally that shouldn't be a problem as even newer WiFi access points etc. still support 2.4GHz.

Again follow the instructions to connect the unit to AirGradient's dashboard and it just works.

It is possible to better calibrate the PM2.5 sensor for low levels (the unit should be placed outside or next to an open window to read the local base environment and left for 20 minutes to calibrate.

The indoor units cost $195 fully assembled, or $138 as a kit and the outdoor unit is $190 assembled and $125 as a kit directly from AirGradient.

There's also shipping to add (from Thailand), but sub $200 for a pretty reasonably accurate air quality monitor is pretty reasonable.

If you happen to be interested in you indoor or outdoor air quality environment, definitely recommended (and with all the integrations available suitable for geeks who want to do their own stuff too).

NOTE: there are other GPIO pins exposed so other sensors could be added and then new firmware adapted to support them.

Nank get real with OE mix True Wireless Earphones

Nank (previously known as Naenka) has been big in the bone conduction earphone space, now there's a move to open ear and the first True Wireless earphones the OE Mix.

Nank OE Mix box

The box contains the earphones in their case, a USB A to USB C cable and an instruction manual.

Open Box

The earphones are light, weighing in a 6.7g each (i.e. left and right) and are coated with a non-skin irritable silicon.

Open case

Bluetooth is now at version 5.4 and supports 60mS latency for gaming. Battery life is 24 hours (but each earphone will hold charge for 6 hours and then has to be put in the case to recharge). Whilst charging the LED on the case flashes red and turns green when fully charged.

Earphones

The drivers have a 0.0096mm diaphragm and support Super Base 2.0 (Nank's terminology).

Earphones

There aren't any physical buttons on the earphone, but they are touch sensitive and touching the left and right top of the earphone perform the following: -

Double touch L/R - switch between music and call.

Single touch L - volume down

Single touch R - volume up

Long touch L - rewind

Long touch R - fast forward

Long touch L/R (1.5s) - call hangup

Triple touch L/R - microphone

The first thing you notice (well don't notice) is how light they are. It can feel a bit awkward placing them over the ear in the correct position, but when they are there, they are very comfortable. Though they stay in place, they can easily be knocked off by say brushing your hand against them while doing something else.

When removed from the case, the earphones turn on and will automatically connect to the device they're paired with (the first time they turn on they will automatically go into pairing mode). When put back into the case they will start charging and the case green light will flash. The earphone turn themselves off - though they can be turned off by touching them for a longer time i.e. over 1.5 seconds - they tell you they're turning off. Though as soon as they are removed from the charger they turn themselves on again.

The earphones are IP55 rated and survive getting wet from sweat etc. As they don't completely cover the ear, you can still hear your environment, so these are good for activities like cycling or running. They can't be fully immersed in water so aren't suitable for swimming.

The sound quality is very good and there are decent highs and lows (notes) as the earphone speakers are placed just outside the ear canal projecting the sound inwards and unlike other Nank bone conducting earphones don't suffer the issues of some of bass being lost or tickling against the skin.

These are a nice addition to the Nank line and at the website price of £43.32 they aren't going to break the bank.

ConceptDraw Office v10: Taking the "Office" Out of Office Work (In a Good Way)

ConceptDraw OFFICE from CSOdessa has released its 10th version, pretty amazing since Ukraine's been illegally invaded by Russia.

ConceptDraw Office v10 has arrived, and it's shaping up to be a game-changer for visual thinkers across all industries. This productivity suite bundles three powerhouse applications: ConceptDraw MINDMAP, PROJECT, and DIAGRAM (formerly PRO). Let's dive into what makes v10 such a compelling upgrade (or just a compelling purchase).

ConceptDraw has always been known for its intuitive diagramming capabilities, and v10 takes it a step further.  DIAGRAM boasts a sleek interface and an extensive library of pre-built templates and symbols, allowing you to create stunning flowcharts, network diagrams, mind maps, and more –  all with just a few clicks.

One of the biggest strengths of v10 is the seamless integration between the three applications. Brainstorming ideas in MINDMAP? Effortlessly convert them into actionable tasks in PROJECT. Need to present your project plan? Export your data directly into a polished DIAGRAM for maximum impact. This streamlined workflow eliminates the need for juggling multiple programs, saving you valuable time and frustration.

New features are: -

Apple Silicon support and macOS Sonoma so the programs run natively on M series Macs.

Rapid Draw - Сreate diagrams faster than ever with expanded Rapid Draw functionality. You can personalise RapidDraw for creating flowcharts using your customised objects.

Grouped Objects in a Diagram - Editing objects in a group individually is easy. You can use a special command to change one object in a group without affecting the others.

Multi-page Mind Maps - Easily create and design multi-page mind maps. Apply the first page style to the entire multi-page map with one click.

Outline View - View and edit your mind map as a diagram with an updated interface and new editing capabilities.

Micro Reports - A new line of micro-reports to remind your team on project deadlines. Create manually or set up automatic creation of ready-to-send deadline reminder emails.

Export to MS Excel - Export project data to MS Excel spreadsheets "as is", including project schedule, resource allocation, cost data, etc.

Interface improvements - 

New captions on the buttons during apps and solutions installation process.

Built-in Help including instructions on activation, proxy set up, and keyboard shortcuts.

Some of the paid solutions are actually complete packages where some free and paid solutions are bundled.

All the programs are easy to use and offer a sensible alternative to incumbent application from the dominant players and they work well together (though Mindmap, Project and Diagram can be purchased separately).

The current price for ConceptDraw OFFICE 10 £239 (usually £399) May 2024.

Individually ConceptDraw DIAGRAM 17 is £159, ConceptDraw PROJECT 14 is £239 and ConceptDraw MINDMAP 15 is £159 and there is a ConceptDraw MINDMAP 15 & PROJECT 14 which is £319 (which make no sense when the whole suite is £90 cheaper). There are also upgrade options if you own a previous version.

See Clearly, Clean Safely: The TOFARO Visual Ear Cleaner

Another day, another Kickstarter. Who doesn't want an in-ear camera system?

Ever felt like you're flying blind when cleaning your ears? Traditional cotton swabs can be ineffective and even push wax further into the ear canal. TOFARO, a new visual ear cleaner on the scene, promises a safer, more precise clean with the help of a high-definition camera.

Box

TOFARO boasts a 1080p HD camera that transmits a live feed to your smartphone or tablet via a dedicated app. This allows you to magnify and examine the inner ear, ensuring you only clean what needs cleaning. Blurry images are a thing of the past, thanks to TOFARO's advanced lens technology.

Inside box

Safety is paramount when it comes to ear care. TOFARO features a detachable cleaning head with a built-in storage compartment. This not only keeps the head clean and hygienic but also prevents accidental loss. The 360-degree angle detection and a smart gyroscope ensure you have complete control and can maneuver the cleaning rod precisely within the ear canal.

Silicon scraper

TOFARO is designed to be compact and portable. It can be carried around easily (though would you want to?). It has a WiFi hotspot that you connect your phone/tablet to and then the app simply connects via this.

Camera with cap

Though not a medical device, it's always important to ensure the device is used safely and shouldn't be used if previous problems with any parts of the ear.

Cap removed

Looking inside your ear may show unexpected things and if these are serious seek medical advice rather than poking around and damaging yourself.

Unit twisted, exposing tube and light that is inserted

The silicon scrapers are relatively soft and if placed behind any wax and gently pulled forward, the wax usually comes with it.

USB-C charging

Again, if wax lodged in the ear and doesn't want to move, don't try forcing it, you can do damage to the surrounding area.

In Ear

The above is a view from the camera of a real ear.

It's a novel device with a decent camera (and gyroscopic stabilisation if required).
