Description
Have you ever wondered how good air quality is in your living room? Or do you need proof of why you fall asleep in an unventilated meeting room after 3 hours? Look no further! This DIY experimental kit has all the answers!
The Earth Listener is an arduino-based sensor device that reads multiple environmental values to indicate air quality. This kit is assembled in 15 minutes and does not require a soldering iron! Simply connect the parts and wires, put everything in the case and connect it to a 5 V USB socket. The MEGA development board is pre-programd and shows ECO2, TVOC (airborne particles), barometric pressure, temperature and humidity values on the TFT touch screen. After the peak, the Earth Listener is also a flash detection sensor. When the flash (or electronic discharge) is detected, the Earth Listener produces an alarm tone and logs on how far the flash is. Since everything is open source, you can add an additional 6 sensors to the earth listener via the sensor label. Logging is possible via the Micro SD card (not included).
