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

05-05-2016 · Example: Gas Sensor with Arduino. In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. Parts needed: So, for this example, you’ll need: 1 x MQ-2 gas sensor

Ks0045 keyestudio MQ-7 Carbon Monoxide Gas Sensor ...

The gas sensitive material used in MQ-7 gas sensor is SnO2, which is of lower electrical conductivity in clean air. It detects carbon monoxide with low temperature (heated by 1.5V) through high-low temperature cycles. The electrical conductivity of the sensor increases with the increase of the carbon monoxide concentration in the air.
