MQ gas and air quality sensors - Olimex

In this example, we would use SNS-MQ2. Yet, a sensor alone can't provide us with any information about the air. The sensors described in the previous chapter would not work in stand-alone mode. They lack a general-purpose microcontroller. They need a host board to send data to. The host board would also provide power to the sensors. How to chose a board suitable for the sensor? The sensors ...

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 ...
