This product is not available in your location yet

Description: 1. The MQ-7 Gas Sensor is a selective gas sensor designed specifically for detecting Carbon Monoxide (CO) in various applications, including home appliance CO detectors and automotive CO sensors. 2. It operates on the principle of electrical conductance: When CO gas is present, it changes the resistance of the sensing element, which in turn alters the sensor's output. 3. The MQ-7 features a high sensitivity towards CO gas with a detection range from 10 to 250 ppm, making it suitable for early warning applications. 4. It is designed for easy integration into various IoT projects and systems using analog input channels, requiring no external power supply or calibration. 5. The MQ-7 sensor has a durable construction with a ceramic heating element, ensuring long-term stability and reliable performance in harsh environments. 6. Its operating temperature ranges from 20°C to 80°C with an optimal sensing range at around 30°C, making it suitable for use in various settings. 7. The MQ-7 s
