Quick Overview 

1. Dual signal output (analog output and TTL level output)
2. The TTL output effective signal is low.
3. Analog output 0 ~ 5V voltage, the higher the concentration the higher the voltage.
4. Good sensitivity to hydrogen sulfide, liquefied gas, natural gas, city gas, and smoke.
5. with long service life and reliable stability
6. fast response recovery characteristics

Product Description

        The sensitive material of the MQ136 gas sensor is SnO2, which with lower conductivity in clean air. When the target Hydrogen sulfide gas exists, the sensor’s conductivity is higher along with the Hydrogen sulfide concentration rising. Please use a simple electric circuit, Convert the change of conductivity to correspond output signal of gas concentration. MQ136 gas sensor has a high sensitivity to Hydrogen sulfide, Low sensitivity for other combustible gas. It is at a low cost and suitable for different applications.

Applications:

• Domestic Hydrogen sulfide detector
• Industrial Hydrogen sulfide detector
• Portable Hydrogen sulfide detector
