The MQ-136 hydrogen sulfide (H2S) gas sensor is designed for detecting low concentrations of hydrogen sulfide gas in the air. It’s commonly used in industrial safety applications where monitoring of H2S levels is critical for personnel safety and environmental compliance.
Specifications:
- Gas Detection: Specifically detects hydrogen sulfide (H2S) gas.
- Measurement Range: Typically detects concentrations from several parts per billion (ppb) to several parts per million (ppm).
- Output: Analog voltage output, varying with the concentration of H2S detected.
- Power Consumption: Operates on low power, suitable for continuous monitoring applications.
- Operating Voltage: Typically operates at 5V DC.
- Response Time: Provides quick response to changes in H2S concentration.
Physical Characteristics:
- Size: Small and compact, suitable for integration into gas detection systems.
- Mounting: Available in through-hole or surface-mount configurations.
- Durability: Designed to withstand industrial environments.
Additional Features:
- Temperature and Humidity Compensation: Includes compensation mechanisms for environmental factors.
- Longevity: Long lifespan with stable performance over time.
- Calibration: Requires periodic calibration to maintain accuracy.
The MQ-136 sensor is ideal for applications such as gas leak detection in industrial settings, monitoring air quality in enclosed spaces, and ensuring safe working conditions where exposure to hydrogen sulfide gas could pose health risks.
