The MQ 6 gas sensor is used as LPG, butane and propane sensor to generate alarm when there are leaks of these gases from the source. MQ6 is a gas sensor very sensitive to gases based on petroleum, but less sensitive to alcohol and carbon dioxide. This simple sensor can be installed in the kitchen to give warning alarm if there is LPG leakage. The MQ6 gas sensor is a 6-pin device and requires a maximum of 5 volts DC that is derived from a Zener-based power supply. There is a heating element inside the sensor that heats up to 5 volts and remains at rest. When the sensor detects gas molecules between 100 ppm and 1000 ppm in the atmosphere, its output becomes high and activates T1 to activate the buzzer. The red LED indicates the high output of the sensor.
The structure and configuration of the MQ-6 gas sensor composed of the micro ceramic tube AL2O3, the tin dioxide-sensitive layer (SnO2), the measuring electrode and the heater are fixed in a crust made by the plastic net And stainless steel. The heater provides the working conditions necessary for the work of the sensitive components. The MQ-6 wrapped has 6 pins, 4 of them are used to search for signals, and another 2 are used to provide heating current.
