Help with CO2 sensor hookup - Interfacing - Arduino Forum

May 06, 2021· Since I have a the Futurlec MG811 CO2 Sensor I should try and use it. (plan A) I could use the Senseair as plan B (backup). I will order what ever you think is easiest to use with Arduino and the Futurlec MG811 CO2 Sensor? jcl, might chime in as well on this . . . If I could be guided through it would be great. Pick a something and I will order

Guide for MQ-2 Gas Sensor with Arduino | Random Nerd Tutorials

May 05, 2016· The MQ-2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...
