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 ...
