MQ136 Hydrogen Sulfide Detection Module in Pakistan

Characteristics of Hydrogen Sulfide Detection Sensor:   1 it has a signal output indication. 2 it consists of dual signal output (analog output and TTL level output) The output signal of 3 its TTL is low. When the output is low and the signal light can be directly connected to the microcontroller 4 its analog output 0~5V voltage, the higher the concentration, the higher the voltage. 5 it can detect hydrogen sulfide, liquefied petroleum gas, natural gas, city gas, the smoke has good sensitivity. 6 it has long service life and reliable stability 7 it has the characteristic of fast response recovery
