LiV Pi Indoor Air Quality Monitor
LiV measures CO2, temperature, humidity and air pressure. While air pressure is not related to indoor air quality, we hope that users will find barometric pressure measurements to be a valuable feature on this device.

Components
LiV's components are very popular with the Raspberry Pi and Arduino communities.
- DHT22 temp/humidity sensor ( -40 to 80°C temperature readings: ±0.5°C accuracy, 0-100% humidity readings: 2-5% accuracy)
- BMP 180 air pressure sensor (high relative measuring accuracy of 0.12 hPa, low temperature coefficient, low noise)
- K30 CO2 sensor (measurement range: 0 – 10,000 ppm, accuracy: ± 30 ppm ± 3 % of measured value within range)
- 1602 I2C LCD Screen (2 lines, 16 characters per line, I2C interface)
- DS3231 Arduino module (accuracy: ±2ppm from 0°C to +40°C, ±3.5ppm from -40°C to +85°C, which is less than 1 minute per year). Please note that this is a modified module for use with Raspberry Pi, with the 5V pull-up resistors removed.

LiV can connect to Instant Messaging applications
LiV is an Internet connected device. If you use an Instant Message client to chat with your buddies, chances are that your IM application supports Jabber/XMPP protocol. You can configure LiV so that it will respond with real-time measurement data to the text commands you send from your IM client application. LiV can also send you notifications when alarms thresholds that you set up were exceeded.

LiV is developer-friendly
Users can replace existing sensors or add new sensors. Preferred method to connect new sensors is by I2C bus.
Developers can extend functionality and add new features (Python programming language).
