MQ136 Gas Sensor Module (Hydrogen Sulfide)

MQ-136 Gas Sensor Module (Hydrogen Sulfide) MQ136

Specification:

ขนาด: 32 X 22 X 24mm (L * W * H)

ชิบ: LM393, MQ-2 gas sensor probe

แรงดัน: DC 5.0 - 5.5V

 

Characteristics:

Output: analog output and TTL level output

- TTL output valid signal is low, which can be accessed directly connected to the microcontroller IO port

- anlog output voltage 0 - 5V, the higher the voltage the higher the concentration.

 

 

MQ136 Sensor:

Sensitive material of MQ136 gas sensor is SnO2, which with lower conductivity in clean air. When the target H2S gas exist, the sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.

 

MQ136 gas sensor has high sensitity to H2S, also could be used to detect other vapor which contains Sulfur. It has low sensitivity to normal combustible gases, which is with low cost and suitable for different application.

 

 

Character:

Good sensitivity to H2S

Long life and low cost

Simple drive circuit

 

 

Application:

Domestic H2S concentration detector

Industrial H2S leakage detector

Portable H2S detector
