MQ-136 Hydrogen Sulfide Gas Sensor Module

The MQ-136 Hydrogen Sulfide Gas Sensor Module is designed to detect hydrogen sulfide gas with a sensing range of 1-200ppm. It provides both analog and TTL level digital outputs, making it compatible with a wide range of microcontrollers and platforms like Arduino and Raspberry Pi. Here are its features, specifications, and applications:

  Features:  

• Dual signal output: analog and TTL level
• Low TTL output signal when effective (light indicates low output, can be directly connected to microcontroller)
• Analog output voltage increases with concentration
• High sensitivity to hydrogen sulfide, liquefied gas, natural gas, city gas, and smoke
• Fast response and recovery characteristics
• Main chip: LM393, ZYMQ-136 gas sensor
• Long life and reliable stability
• Simple drive circuit

  Specifications:  

• Model: MQ-136
• Target Gas: Hydrogen Sulfide (H2S gas)
• Detecting Range: 1-200ppm
• Length: 29 mm
• Width: 19 mm
• Height: 24 mm
• Weight: 8 grams

  Applications:  

• Domestic hydrogen sulfide detector
• Industrial hydrogen sulfide detector
• Portable hydrogen sulfide detector

  Package Includes:  

• 1 x MQ-136 Hydrogen Sulfide Gas Sensor Module

The MQ-136 sensor module is suitable for various applications where monitoring hydrogen sulfide gas levels is necessary, such as in industrial settings, domestic environments, and portable gas detection devices.
