Ever wondered how good the air quality is in your living room? Or do you
need proof of why you fall asleep in a non-ventilated 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 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 thing 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)
The Earth Listener needs a burn-in time of 48 hours and at least 20
minutes of logging before the eCO² and TVOC values are stable. This
experimental kit is for indicative purposes only. Values should be
interpreted while considering the environmental situation. Keep your
living space well ventilated.
