Guide for MQ2 Gas Sensor with Arduino | Random Nerd Tutorials

20160505· The MQ2 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 it returns 0 with 0V. Any voltage in …
