Arduino Powered Pollution Sensor System Instructables

MQ135: It is a simple sensor used to measure presence of some common pollutants like NH3, NOx, Alcohol, Benzene, Smoke, CO2. It has 4 pins, two for power supply and 2 for analog and digital readings. Sharp GP2Y1010: is an optical dust sensor which measures the volume of suspended dust particles in air by using a LED and phototransistor. It has 6 pins.


CO2 Monitoring with K30 Sensor Arduino Project Hub

20/6/2017· Overview. This project is about monitoring CO2 levels at home, in the greenhouse, in that small office, etc. Some time ago I started working on an open source Raspberry Pi indoor air quality monitor called LiV tried a number of analog CO2 sensors for that project, but I ran into calibration issues until I got a K30 CO2 module.

Adafruit CCS811 Air Quality Sensor

15/11/2021· return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. This sensor is not well supported on Raspberry Pi. This is because it uses I2C clock stretching which the Pi cannot do without drastically slowing down the I2C speed. CircuitPython and Arduino are supported.
