Description:
Size: 32mm X22mm X24mm
The main chip: LM393, MQ-9 gas sensor
Work voltage: DC3-5V
With the signal output instructions;
Dual output (analog output, and TTL level output);
TTL output valid signal is low, the microcontroller can be connected directly;
0 ~ 5V analog output voltage, the higher the voltage the higher the concentration;
Detect carbon monoxide, combustible gas has a good sensitivity
With a long life and reliable stability;
Fast response characteristics;
Application:
For home or factory gas leak monitoring devices, suitable for carbon monoxide, combustible gas monitoring device, can test carbon monoxide, combustible gas 10 to 1000ppm CO, 100 to 10000ppm range
