Description
MQ-7 MQ7 Gas Sensor Carbon Monoxide CO Gas Alarm Sensor Detection Module For Arduino New
Features
Suitable for home or factory to detect carbon monoxide gas.
High quality dual-panel design, with power indicator and TTL signal output instructions.
DO switching signal (TTL) output and AO analog signal output.
TTL output valid signal is low. (When the output low signal is on, it can be directly connected micro-controller or relay module.)
Analog output voltage: the higher concentration, the higher voltage.
Have better sensitivity to carbon monoxide.
Four screw holes, easy positioning.
Long life and stability, quick response and resume.
