The MQ-136 Hydrogen Sulfide Gas Sensor can be used to monitor the concentration of hydrogen sulfide gas. This module simplifies using the MQ-136 gas sensor by providing digital as well as analog output, which can be interfaced with microcontrollers, Arduino, and Raspberry Pi.
The sensitive material of the MQ136 gas sensor is SnO₂, which has lower conductivity in clean air. When the target hydrogen sulfide gas exists, the sensor’s conductivity is higher along with the rising hydrogen sulfide concentration. Please use a simple electric circuit and convert the change of conductivity to correspond to the output signal of gas concentration. The MQ136 gas sensor has a high sensitivity to hydrogen sulfide and low sensitivity for other combustible gases. It is at a low cost and suitable for different applications.
Applications:
Domestic Hydrogen sulfide detector
Industrial Hydrogen sulfide detector
Portable Hydrogen sulfide detector
Note: Actual product may vary in terms of design; we will ship according to the stock availability.
Features:
1. Dual signal output (analog output and TTL level output)
2. The TTL output effective signal is low. (The signal light is on when the output is low and can be directly connected to the microcontroller.)
3. Analog output of 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
7. Size: 32 mm x 22 mm x 27 mm (length x width X height)
8. The main chip: LM393, ZYMQ-136 gas sensors
9. Good sensitivity to Hydrogen sulfide
10. Long life and low cost
11. Simple drive circuit
Package Includes:
1 x MQ-136 Hydrogen Sulfide Gas Sensor
