MQ-2 Gas Sensor Module

MQ-2 Gas Sensor Module

Flammable Gas Lpg and Smoke Detector 300-10000ppm MQ2 Butane Propane Fire Alarm

     It is used for detecting smoke and flammable gases in the air. As the flammable gas density increases its conductivity increases. Accordingly it produces a signal from its analog and digital outputs. It works with DC 5V. It can be used with mcu kits such as Arduino. It is suitable for use in areas such as home factory workplace warehouse. The product is hot while working, this situation is normal.
