Project is still in development mode so v1.0, not yet tested PCBs are in ordering process so anything u do do it on your own, i'm not responsibe for bad pcbs and mistakes !
This is open source air quality device that i started hence the polluted air in Sarajevo, this project is made for all makers all around the world to spread the awareness of polluted air.
For this project i plan to make :
- Web app so you can see big data screen
- Mobile app for tracking the data
- 3D printed enclosure
- Connect device with smart home ( Google & Alexa)
- Who know what more u can do with this hardware feel free to play :D
- Measure Temperature & Humidity
- Measure Pressure & Altitude
- Measure PM2.5 , PM10 , PM1.0
- Has smart leds so you can play with different colors
- Gyroscope and Accelerometer ( so you can play with different orientation of device)
- Battery charging circuit
- Wifi and BLE
- Circuit to measure health of battery
- Dimensions is 47x36mm, pretty small !
- And you can programm the device via USB type C :)
- Add power switch on usb so when charging device it will work via usb power.
- High side mosfet for ws2812 as they draw current while being off
- Add CO electrochemical sensor (this need testing electronic first)
- Make it smaller use pmsa003, because why not :)
- Use sk6812 side led to save some space and to have side emitting leds
