MQ2 Reading different gases Sensors Arduino Forum

20210506· MQ2 Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.


Manual SparkFun Electronics

MQ3 Test Circuit Instructions: The above fig is the basic test circuit of sensor requires two voltage inputs: heater voltage (V H) and circuit voltage (V C). V H is used to supply standard working temperature to the sensor and it can adopt DC or AC power, while V RL is the voltage of load resistance R L which is in series with sensor. Vc supplies the detect voltage to load resistance ...
