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. For this tutorial, I will be …

07/10/2018· MQ-3 Equivalent Sensors. MQ-2, MQ214 (detection of Methane), MQ303A . Brief Detail about MQ-3 Gas Sensor. MQ-3 module is suitable for detecting Alcohol, Benzine, CH 4, Hexane, LPG, material of MQ-3 gas sensor is SnO 2, which with lower conductivity in clean the target alcohol gas exist, the sensor’s conductivity is more higher along with the gas concentration rising.
MQ-7 sensor features. The MQ-7 sensor has high sensitivity to carbon monoxide. The gas sensing layer on the sensor unit is made of Tin dioxide (SnO2), which has lower conductivity in clean air. The conductivity increases as the levels of Carbon monoxide rise. The detection range of the sensor is 20ppm-2000ppm of CO. Calibrating the sensor
