The MQ-136 is a highly sensitive gas sensor designed for detecting hydrogen sulfide, liquefied gas, natural gas, urban gas, methane, alcohol, and smoke. Using an LM393 comparator chip and ZYMQ-136 gas sensor, the module provides both analog and TTL outputs, offering flexibility for various applications. With a DC 5V working voltage, the sensor features good sensitivity and fast response/recovery characteristics, making it ideal for gas leak detection in both households and industrial settings. It requires a 20-second warm-up for stable operation and has a long-lasting, reliable service life.
Key Features:
- Dual Output Signals: Provides analog and TTL outputs, offering versatile integration options.
- TTL Output: Outputs a valid signal at low level, easily connected to microcontrollers or NPN transistors.
- Analog Output: Voltage increases with gas concentration (0-5V range).
- High Sensitivity: Detects hydrogen sulfide, liquefied gas, methane, alcohol, and smoke effectively.
- Long Service Life & Stability: Reliable performance with long-term durability.
- Fast Response & Recovery: Quickly reacts to changing gas concentrations.
Applications:
- Gas Leak Detection: Ideal for use in households and factories to monitor gases like liquefied gas, methane, alcohol, smoke, and more.
- Microcontroller Projects: Suitable for SCM learning, electronic competitions, and product development.
- Environmental Monitoring: Used in systems requiring accurate gas detection and alert mechanisms.
