Arduino lesson – MQ-7 Gas Sensor «

15/11/2018· Introduction to MQ-7 Carbon Monoxide Sensor. According to its datasheet, the MQ-7 carbon monoxide sensor detects 20 to 2000 ppm of CO in air. Here is its sensitivity characteristic curve: This is a graph of Rs/R0 vs. gas concentration in ppm. Rs is the resistance of the sensor in target gas while R0 is the resistance in clean air. We will use this graph later when we create our code. This ...
