MQ-136 Hydrogen Sulfide (H2S) Gas Sensor Module
Detect the presence of toxic Hydrogen Sulfide gas with the specialized MQ-136 Gas Sensor Module. This sensor is engineered for high sensitivity to Hydrogen Sulfide (H2S), a dangerous gas commonly found in industrial settings, sewage systems, and agricultural environments. It’s an essential component for building safety and air quality monitoring devices.
The MQ-136 is ideal for creating H2S alarms and environmental monitors. This easy-to-use breakout board includes all necessary supporting circuitry, featuring a versatile dual-output system. The **Analog Output (A0)** provides a real-time voltage reading proportional to the H2S concentration, while the **Digital Output (D0)** acts as a simple alarm, triggering when the concentration surpasses a user-defined threshold.
This trigger point can be precisely calibrated using the onboard potentiometer, allowing you to customize the sensor’s sensitivity for your specific safety application. For any project requiring dependable H2S detection, the MQ-136 is a reliable and effective choice.
