New Air Quality Sensor
Log from Remote Smoke Detector
Well my two new sensors arrived from mouser today. I wired up the I2C version and quickly got it talking to my arduino. I'm calling this iteration 'version 2'. The chip is sending me valid data so I know I didnt fry it when hooking it up. I have yet...

Getting Air Quality Data to the Map & Reverse Geocoding
Log from The Interactive Air Quality Map
The Air quality map currently gets all its air quality data from the DesignSpark Environmental Sensor Development Kit (ESDK), the data is being reported via MQTT to the Arduino WIFI 1010 on the map, the map reacts to data on a per area basis, and although...

Air quality sensor selection
Log from Street Sense
Measuring street level pollutants that affect human health is the focus. The sensor selection is guided by looking at the risks imposed by various pollutants. Health risks, at the street level, prioritized Particulate matter (PM)Ozone...

New CanAirIO Air Quality Sensors Library
Log from CanAir.io Air Quality Network
We released a new sensors library for PlatformIO and Arduino library managers. The idea with this libraries is handling some particle meter (PM) sensors, like Honeywell, Plantower, Panasonic, Sensirion, and others compatible with UART communication,...

Adding sensors: Air Quality
Log from MakeTime
Adding a CCS811 sensor, in addition to the SHT31 MakeTime can indicate equivalent total VOC (eTVOC) levels.Sensor readings are transformed to ug/m^3 and the full scale displayed reads from 0 to 1000 ug/m^3. The higher the reading, the more the display...

New Compressed Air Fittings and Lines
Log from Thermoforming Machine Rebuild
We've just completed the milestone of replacing the compressed air fittings and lines in the machine. We replaced the fittings because we expect the old air seals within them to have decayed with age. Since we have everything disassembled, replacing...

Sensor Tile as an air quality sensor
Log from STM32L4 Sensor Tile
07/08/17The latest experiment was a partial success. I essentially repeated the last experiment but placed the Sensor Tile outside the house, near the threshold on a portico support pillar out of the sun. Disappointingly, the first several hours of data...

MiCS-VZ-89T a low power air quality sensor
Log from Portable environmental monitor
Putting everything together also requires checking everything separately first. So I did with the MiCS-VZ-89T sensor, and here is the story, also presented on my blog: MiCS-VZ-89 Air Quality SensorA low power sensor that can measure at the same time...

03: Refreshing Air Quality (Carbon Filter Mod)
Log from Elegoo Mars 3 "Pro"
The new Pro printer comes with carbon activated filters that can remove some (all?) of the resin smell. While some people think that these filters are useless. It wouldn't be called Pro if we wouldn't at least try to replicate the same feature...

Project Log 63: DIY Iron-Air Battery.¹
Log from DIY Mech/Exoskeleton suit.
Friday, 14/07/2023, 17:53. Although I talk a lot how Iron-air batteries are really similar to alkaline hydrogen fuel cells, I didn't look too much on scientific articles building iron-air batteries and neither would ChatGPT, since its data-base is still...

Project Log 65: DIY Iron-Air Battery.²
Log from DIY Mech/Exoskeleton suit.
21/07/2023, Friday, 18:50. Well, hello, this is me from the future and I need to add some informations about Iron-Air battery. The theoretical energy density of iron-air battery is in the range of 1200 wh/kg and I optimiscally assumed that...

A first attempt at figuring out the MAX30105 Air Particle Sensor
Log from Iteration 8
One of the areas of sensing that I don't have a lot of experience with is atmospheric sensing. While I've become familiar with sensors for temperature, pressure, and humidity, I am largely inexperienced with the array of sensors available for sensing...

Enclosure
Log from The Air Quality Wing
If you’re wondering, yes there’s an enclosure! Many thanks to the designer, Nicholas, for taking the time to make this amazing enclosure. Provided courtesy of Nicholas. You can print your own by downloading the STL files in this Github repository....

LED removal
Log from Simple web enable air quality sensor
I am looking into using the LED on the Photon to indicate air quality. You can override the RGB light on the board to light whatever color you want. Might give it a go. This would make the external LED not needed.
