Velleman Earth Listener

Description

• Earth Listener by Velleman
• Offers a 2.8-inch color touch screen
• Detects lightning or electronic discharge up to 40 km away
• Measures the environmental values eCO2, TVOC, and more
• Specially designed hardware with pre-programmed software
• Stylish wooden enclosure
• Open source and fully Arduino based
• Implemented logging function on SD card (Not Included)

The Velleman Earth Listener is an Arduino-based sensor device that reads multiple environmental values to indicate the air quality. This kit is assembled in 15 minutes and you don’t need a soldering iron, just 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 shows eCO2, TVOC (particles in the air), barometric pressure, temperature, and humidity values onto the TFT touchscreen. To top things off, the Earth Listener also contains a lightning detection sensor.

If lightning (or electronic discharge) is detected, the Earth Listener will give an alarm tone and log how far the lightning is located. Since everything is open source, you can add an additional 6 sensors to the Earth Listener via the sensor shield. Logging is possible via the micro SD card (not included).
