MQ136 Gas Sensor can be used to monitor the concentration of Hydrogen Sulfide gas (H2S). This Module simplifies using the MQ-136 gas sensor by providing digital as well as analog output which can be interfaced to Microcontrollers, Arduino and Raspberry pi.Senitive material of MQ136 gas sensor is SnO2, which with lower conductivity in clean air. When the target Hydrogen sulfide gas exist, the sensor’s conductivity is higher along with the Hydrogen sulfide concentration rising.
Main chip: LM393, ZYMQ-136 gas sensors
Working voltage: DC 5V
Signal output instructions.
Dual signal output (analog output and TTL level output)
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)
Analog output 0 ~ 5V voltage, the higher the concentration the higher the voltage.
Good sensitivity to hydrogen sulfide, liquefied gas, natural gas, city gas, and smoke.
long service life and reliable stability
fast response recovery characteristics
Gas leak monitoring device suitable for home or factory, suitable for liquefied gas, butane, propane, methane, alcohol, hydrogen, smoke and other monitoring devices.
Applicable occasions: MCU learning, electronic competition, product development, graduation design.
