Earth Listener

• Measures environmental values such as CO2, TVOC, barometric pressure, temperature and humidity
• Detects lightning or electronic discharge up to 40 km away
• Development board with microcontroller ATmega2560
• Displays values on a 2.8-inch color touch screen
• Implemented logging function on SD card (SD not included)

The Earth Listener is an Arduino-based sensor device that reads multiple environmental values to indicate air quality. This DIY experimental kit is easy to assemble in 15 minutes, without the need for a soldering iron. Simply connect the parts and wires, put everything in the case and connect it to a 5V USB socket. The Mega development board is pre-programmed and will display eCO2, TVOC (particles in the air), barometric pressure, temperature and humidity values on the TFT touchscreen. Additionally, the Earth Listener also contains a lightning detection sensor. If lightning (or electronic discharge) is detected, the Earth Listener will sound an alarm and log the distance the lightning is located. As the kit is open source, you can add an additional six sensors to the Earth Listener via the sensor shield. Logging is also possible via the micro SD card (not included). *Arduino compatible 3 colour RGB SMD LED module not included.
