Introduction to the MQ-5 Gas Sensor
The MQ-5 Gas Sensor is a powerful and affordable solution for detecting gases like LPG, methane, and natural gas. This sensor is widely used in various safety applications, IoT projects, and smart home systems. Its high sensitivity and rapid response time make it an ideal choice for ensuring safety in environments prone to gas leaks.
How Does the MQ-5 Gas Sensor Work?
The MQ-5 gas sensor works on the principle of electrochemical sensing. When gases such as methane, LPG, or natural gas come into contact with the sensor, it changes its resistance based on the concentration of the gas. This resistance change is then converted into a readable output signal, which can trigger alarms or other responses.
Key Technical Insights:
- The sensor operates between 5V DC and 20V DC.
- It provides both analog and digital output.
- The preheat time is around 24 hours, ensuring accurate readings.
