ACEIRMC 5pcs MQ-7 Gas Sensor Detector Monitor Module for Arduino Raspberry Pi ESP8266 MQ-7 5V DC (MQ-7)
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•MQ-7 Gas Sensor Detector Carbon Monoxide Monitor Module
•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,
