MQ-136 Hydrogen Sulfide H2S Gas Sensor Module
4,200.00DA
Price in reward points: 4200
The MQ-136 Gas Sensor Module is designed to detect Hydrogen Sulfide (H2S) gas in the air. Highly sensitive with a fast response time, this module provides both analog output (for precise concentration measurement) and digital output (with adjustable threshold via potentiometer). It is ideal for environmental monitoring, industrial safety, air quality control, and gas leak detection projects using Arduino, Raspberry Pi, or other microcontrollers.
Key Features:
• High Sensitivity to H2S: Specifically calibrated to detect hazardous Hydrogen Sulfide gas concentrations.
• Dual Output Modes: Analog output (AO) for quantitative concentration levels and Digital output (DO) for alarm triggering.
• Adjustable Threshold: Onboard potentiometer allows easy adjustment of the digital detection sensitivity.
• Fast Response & High Stability: Fast recovery time with reliable performance and long operational life.
• Easy Integration: Standard 4-pin interface compatible with Arduino, ESP32, and STM32 development boards.
Specifications:
• Target Gas: Hydrogen Sulfide (H2S)
• Detection Range: 1 – 200 ppm H2S
• Operating Voltage: 5V DC
• Sensor Type: Semiconductor (SnO2)
• Output Types: Analog & Digital (TTL)
