Gas Sensors

The MQ-136 Gas Sensor is designed to detect hydrogen sulfide (H₂S), a toxic and corrosive gas commonly found in industrial and waste environments. It features high sensitivity and stability, making it suitable for safety systems in oil refineries, sewage treatment plants, and chemical industries. The sensor ensures early warning of hazardous gas leaks, helping maintain safe working conditions.

The MQ-137 Gas Sensor is used for detecting ammonia (NH₃) gas in various environments. It is highly sensitive to ammonia while maintaining moderate resistance to interference from other gases. This sensor is ideal for agricultural applications, refrigeration systems, industrial leak detection, and environmental monitoring. With fast response and recovery times, it provides reliable performance for real-time gas detection systems.

The MQ-138 Gas Sensor is a versatile sensor capable of detecting a range of gases including benzene, alcohol, smoke, and other volatile organic compounds (VOCs). Its broad detection capability makes it suitable for indoor air quality monitoring, safety systems, and research applications. The sensor offers good sensitivity and quick response, making it an excellent choice for multi-gas detection projects.

The MQ-139 Gas Sensor is designed for detecting harmful gases and volatile organic compounds (VOCs) in the air. It is particularly useful for monitoring indoor air pollution levels in residential, commercial, and industrial environments. With stable performance and long operational life, it is widely used in smart air quality systems and environmental monitoring devices.

The MQ-2 Gas Sensor is a widely used multi-gas sensor capable of detecting smoke, LPG, methane, hydrogen, and carbon monoxide. It offers high sensitivity and fast response, making it ideal for gas leakage alarms and safety systems in residential and industrial environments. The sensor operates using SnO₂ semiconductor technology, where conductivity increases with gas concentration.

The MQ-214 Gas Sensor is designed for detecting methane and LPG in industrial environments. It provides improved stability and durability compared to standard MQ sensors, making it suitable for continuous monitoring applications.
