Description
MQ-136 Hydrogen Sulfide (H₂S) Gas Sensor Module
The MQ-136 Gas Sensor Module is designed for monitoring the concentration of Hydrogen Sulfide (H₂S) gas with high sensitivity and reliability. Based on a SnO₂ semiconductor sensing element, the sensor exhibits low conductivity in clean air and increased conductivity when exposed to hydrogen sulfide gas, allowing accurate detection through simple signal conversion circuits.This module simplifies the use of the MQ-136 sensor by providing both analog and digital (TTL) outputs, making it easy to interface with Arduino, Raspberry Pi, and other microcontrollers. With fast response and recovery time, long service life, and low cost, it is suitable for a wide range of domestic and industrial safety applications.
Note: Actual product design may vary depending on stock availability.
