All about MQ sensors || MQ-2, MQ-3, MQ-5 sensor || Construction, Working, interfacing with Arduino

Welcome to channel

In this video I’ve explained construction , working and interfacing of MQ-2, MQ-3, MQ-5 sensors.
There are so many types of sensors available in MQ series which uses for detecting presence of alcohol, LPG and other various gases .

Watch complete video for getting understanding of how MQ sensors works and how to interface it with arduino
