MQ-2 Gas Sensor Module Smoke Hydrogen Butane LPG Methane Detector for Arduino

Description: MQ-2 Gas Sensor Module Smoke Hydrogen Butane LPG Methane Detector This module is a Gas sensor sensitive to many gases that can detect many types of gases, such as smoke, methane, carbon dioxide and other gases. You can use this module together with your favourite MPU such as the Arduino for projects that involve the detection of smoke or gas leaks. The module sends an analogue output to the MPU with the amount of gas detected. It uses an interlock connector for ease of use. It has an adjustable resistor on-board to calibrate the output signal. We highly recommend to connect this module to our Sensor shield for Arduino for maximum compatibility with our products. Specification: Dimensions: 19.5mm x 45mm x 18mm Input Voltage: 5v Detects smoke, methane, carbon dioxide, butane, and other gases Digital I/O: 1 What you will receive: 1 x MQ-2 Gas Sensor Module Smoke Hydrogen Butane LPG Methane Detector
