Air Pollution Monitoring System using Arduino and MQ135 ...

05/10/2018· Arduino Air Quality Monitor I ... While not the nicest CO2 sensor (I like the COZIR Ambient) they do have the benefit of being really cheap (for a true CO2 sensor) and when compared with better sensors are accurate enough for this kind of project. The device has a number of interfaces, but I used the TTL serial interface. This just requires 4 pins from the device (19-Tx, 18-Rx, 17-GND, 16-5V ...
