MQ-7 CO sensor module, gas sensor

Product Description

2064    MQ-7 CO sensor module; gas sensor For Arduino

A working voltage: 5 V DC
B, features:
1, with the directions of the signal output.
2, two-way signal output (analog output, and TTL level output)
3, TTL output valid signal is low. (When low output signal light, and can be connected directly to the microcontroller)
4, 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
5, having a high sensitivity and good selectivity to carbon monoxide.
6, has a long life and reliable stability

C, the application:

Carbon monoxide detection device for home environment. Suitable for the detection of carbon monoxide, gas, etc..
