Description: 1. MQ-7 is a gas sensor module designed specifically for detecting Carbon Monoxide (CO) in various applications, including DIY carbon monoxide detectors and industrial CO monitoring systems. 2. Operating Principle: This sensor utilizes a chemical reaction between the CO gas and a sensitive film coated inside the sensor to produce an electrical output proportional to the concentration of CO present. 3. Sensor Element: The MQ-7 module includes a ceramic heating element, temperature sensor, and the sensitive film coating in a compact, epoxy-sealed housing for durability and protection against moisture and contaminants. 4. Working Temperature: The sensor operates most effectively at temperatures between 25°C and 60°C (77°F to 140°F). Prolonged exposure to temperatures below 0°C or above 85°C may impact performance. 5. Output Signal: When exposed to CO gas, the sensor generates an analog resistance value that can be read and converted to a digital signal using appropriate electronics.
