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
