LIV PI FOR RPI MODEL B HAS BEEN DISCONTINUED. PLEASE CHECK LIV PI SETS FOR RPI MODEL 3/2/B+.

LiV Pi Board is a sensor expansion board that turns your Raspberry Pi into a modern indoor air quality monitoring device that measures CO2, temperature, humidity and air pressure.

• Use it in your living room
• Use it to test the air quality in your bedroom
• Use in in your greenhouse: higher levels of CO2 make plants grow bigger and faster
• Use it in your garage: gasoline and diesel engines give off large amounts of CO2
• Use it in the conference room at work

Detailed LiV information is available at: www.livpi.com

LiV Pi Expert contains: fully assembled LiV Pi board, DHT22 temperature/humidity sensor, BMP180 air pressure sensor, K30 CO2 Sensor, LCD Screen and connection cable, DS3231 Real Time Clock module, 8G SD card with bootable LiV Pi Image. Sensors ship with connectors soldered. No soldering needed.

THE EXPERT KIT INCLUDES THE CO2 SENSOR!!

Assembly instructions are available here .

LiV Indoor Air Quality Monitor

LiV Starter measures temperature, humidity and air pressure. LiV Expert measures CO2, temperature, humidity and air pressure.

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 with the 5V pull-up resistors removed).

LiV Intranet

LiV offers an Intranet website with measurement data visualization.

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 can connect to IoT platforms

Currently LiV can connect to DeviceHive, data.sparkfun.com, Xively, Emoncms, ThingSpeak, analog.io. More to come.

LiV is developer-friendly

• Users can replace existing sensors or add new sensors
• Developers can extend functionality and add new features by writing Python code
• LiV offers a set of APIs for easy integration
• LiV offers a set of REST APIs in JSON format. Developers can easily expand the existing set of APIs with Python Flask.

LiV is open source

LiV is open source hardware and software. LiV's software is released under a MIT license. LiV's hardware is released under a CC BY-NC-SA 4.0 license. Here is Liv on GitHub.
