MQ-136 Hydrogen Sulfide Gas Sensor Module

SKU : A09026 product description: First, size: 32mm X22mm X27mm length X width X height Second, the main chip: LM393, ZYMQ-136 gas sensor Third, the working voltage: DC 5 volts Fourth, the characteristics: 1, with a signal output indication. 2, dual signal output (analog output and TTL level output) 3. The TTL output valid signal is low. (When the output is low, the signal light is on, it can be directly connected to the microcontroller) 4, analog output 0 ~ 5V voltage, the higher the concentration, the higher the voltage. 5. It has good sensitivity to hydrogen sulfide, liquefied gas, natural gas, city gas and smoke. 6, has a long service life and reliable stability 7, fast response recovery characteristics Fifth, the application: Suitable for gas leakage monitoring devices in homes or factories, suitable for monitoring devices such as liquefied gas, butane, propane, methane, alcohol, hydrogen, and smoke.
