PRODUCT INTRODUCTION
MQ-7 Module Carbon Monoxide Gas Sensor Detection Alarm MQ7 Sensor Module for arduino DIY KIT
MQ-7 gas sensor is sensitive material used in clean air, low conductivity tin dioxide (SnO2). Detection method using low temperature cycling (1.5V heating) detect carbon monoxide, airborne sensor conductivity increases with the increase of the concentration of carbon monoxide gas, high temperature (5.0V heating) cleaning stray gas adsorption at low temperature. Using a simple circuit can be changes in the conductivity, concentration of the gas is converted to the corresponding output signal. MQ-7 gas sensor with high sensitivity for carbon monoxide, this sensor can detect a variety of gases containing carbon monoxide, is a low-cost sensors for a variety of applications .
Gas may be used in homes and factories leakage monitoring device suitable for the detection of gas, butane , propane , methane , smoke , etc. ;
