Whadda Earth listeners

Have you ever wondered how good the air quality in your living room is? Or do you need proof of why you fall asleep after three hours in an unventilated conference room? Look no further! This DIY experimental kit has all the answers! The Earth Listener is an Arduino-based sensor that reads multiple environmental values to display air quality. This kit can be assembled in 15 minutes and requires no soldering! Just connect the parts and wires, place everything in the enclosure, and connect it to a 5V USB port. The MEGA development board is pre-programmed and displays ECO2, TVOC (particles in the air), barometric pressure, temperature, and humidity values on the TFT touchscreen. Additionally, the Earth Listener is also a lightning detection sensor. When lightning (or an electrical discharge) is detected, the Earth Listener emits an alarm sound and logs how far away the lightning is. Since everything is open source, you can add an additional six sensors to the Earth Listener via the sensor shield. Logging is possible via the micro SD card (not included). Arduino compatible. 3-color RGB SMD LED module not included.
