Interfacing MQ-2 Gas Sensor with evive - STEMpedia

The MQ2 Gas sensor has a built-in variable resistor that changes its value according to the concentration of gas. If the concentration is High, the resistance decreases, if the concentration is low, the resistance increases. Besides the built-in resistor, it is necessary to include load resistor, Load resistor serve to adjust sensor sensitivity and accuracy, it’s value can range from 2k ohm ...

MQ 2 Gas Sensor - IoCT

In order to connect the MQ 2 sensor to the Raspberry Pi, two other sensors are needed. A level converter is needed to take the 5V output signal to a signal and an A/D converter to be able to read the signal in digital form. It is necessary to step the voltage down because a raspberry pi can only read signals at without potential for damage. The A/D converter changes the analog signal ...
