MQ-9 Carbon Monoxide & Flammable Gas Sensor Module
Previous
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.
Specification:
Input voltage: DC 5±0.2V
Power: 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
Dimensions: 33(L) * 21(W) * 17(H) mm
Wire connecting method:
VCC - positive pole (5V)
GND - negative pole
DO - TTL switch signal output
AO - analog signal output
Package Include:
