We are developing a low cost air quality monitor.
The plan is to make it light weight, ultra portable, and really simple to get the data off of it. This will allow us to make a ton of them have citizen scientists learn more about their own air quality.
After attempting to design our own sensor, we ran into a dead end. We ended up finding an off the shelf partical sensor that kind of worked right away. After adding a fan, and doing some signal processing, we can get a decent signal out of it.
Below is our newest prototype. It has a 128x64 GLCD, temperature, humdity and sound sensor. Bluetooth and a rechargable lipo battery.
In order to make it as cheap as possible, and get to market quickly, we decided to make an in-home unit.
Below is our newest prototype. It's called Speck, it has a 128x64 GLCD, temperature, and humdity sensors. It gets its power, and transfers data over USB.
Below is our latest revision. The display has been upgraded to a 320x240 full color tft lcd with a touch screen. November of this year, we will start a pilot of 150 units.
I also designed a mobile version of the Speck, called GPSpeck. It has the same features as the Speck, with an added GPS and a large battery. November of this year, we will start a pilot of 50 units.
