Iot Relay - Enclosed High-Power Power Relay for Arduino, Raspberry Pi, PIC or WiFi, Relay Shield

The Analog Smoke/LPG/CO Gas Sensor(MQ2) module utilizes an MQ-2 as the sensitive component and has a protection resistor and an adjustable resistor on board.

The MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke.

It could be used in gas leakage detecting equipments in family and industry.

The resistance of the sensitive component changes as the concentration of the target gas changes.

Used for Detecting Smoke, Flammable Gas (e.g. LPG, Methanol , Ethanol) by SnO2 Gas Sensitive Materials
Dimension: 32 mm x 20 mm x 22mm
Input Voltage: 5V DC
Result: Digital DO: 0.1V / 5V [TTL Switch] with DO LED display; Analog AO: 0.1 to 0.3 V [ Higher Value Means Higher pollution ]
