Gas Sensor Mq7

Using high and low temperature cycle
test low temperature heat (1.5 V) carbon
monoxide, sensor conductivity
increases with increasing concentration
of carbon monoxide gas in the air, high
temperature washing the low
temperature heat (5.0 V) stray gas
adsorption. The sensor can detect a
variety of gases containing carbon
monoxide. Mq7 is a low-cost sensor
suitable for many applications
