MQ-5 Methane LPG Liquid Propane Gas Sensor Module

MQ-5 Methane LPG Liquid Propane Gas Sensor Module

Introducing our MQ-5 Methane LPG Liquid Propane Gas Sensor Module, an essential device for detecting gas leaks in both consumer and industrial settings. This sensor module is designed to sense LPG, natural gas, and coal gas, offering reliable performance while excluding responses to alcohol, cooking fumes, or cigarette smoke.

Utilizing SnO2 as its sensitive material, the MQ-5 sensor demonstrates low conductivity in clean air. However, in the presence of combustible gas, its conductivity increases proportionally with the gas concentration. This change in conductivity is converted into an output signal by a simple electric circuit, providing accurate indications of gas concentration.

The MQ-5 sensor exhibits high sensitivity to methane, propane, and butane, making it particularly effective in detecting methane. With an adjustable sensitivity potentiometer, you can fine-tune the sensor to suit your specific application needs.

Operating at 5V DC, this sensor module boasts a range of features, including:

• High sensitivity to LPG, natural gas, and town gas.
• Minimal sensitivity to alcohol and smoke.
• Stability and long lifespan.
• Simple drive circuit.
• Fast response time.

Cost-effective and versatile, our MQ-5 Methane LPG Liquid Propane Gas Sensor Module is suitable for various applications, ensuring safety and peace of mind in environments where gas leaks may occur.
