Smart Electronics MQ-9 carbon monoxide Combustible gas sensor alarm module
MQ-9 carbon monoxide Combustible gas sensor alarm module
Feature:
Size: 32mm * 22mm * 27mm
Main chip: LM393, MQ-9 gas sensors
Working voltage: DC 5 V
Characteristics:
1, having a signal output instruction.
2, dual signal output (analog output, and TTL level output)
3, TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller)
4, 0 - 5V analog output voltage, the higher the concentration the higher the voltage.
5, for CO, gas, liquefied petroleum gas with high sensitivity and good selectivity.
6, has a long life and reliable stability
