MH-711A Carbon Dioxide Sensor Introduction: The MH-711A carbon dioxide gas sensor is a universal intelligent infrared gas sensor that uses the principle of Non Dispersive Infrared (NDIR) to detect carbon dioxide in the air. It has good selectivity, no oxygen dependence, stable performance, and long service life; Built in temperature compensation. This sensor is a compact and high-performance sensor that combines mature infrared absorption gas detection technology with micro mechanical processing and sophisticated circuit design. It can be widely used in industrial field instruments, industrial processes, and safety protection monitoring. Features: 1. High sensitivity, high resolution, low power consumption, and fast response time 2. Provide multiple output methods such as UART and analog voltage 3. Temperature compensation, excellent linear output Technical parameters: Product model: MH-711A Detection gas: carbon dioxide Working voltage: 4.5-5.5V DC Average current:<100 mA Interface level: 3.3 V Measurement range: optional within the range of 0-5% Vol (see Table 2 for details) Output signal: IIC 0.4-2 V Preheating time: 3 minutes Response time: T90 < 30 s Working temperature: -40~70 ℃ Working humidity: 0-95% RH (without condensation) Overall dimensions: Φ 44 mm × 61 mm Weight: 350 g Service life:>5 years Explosion proof sign: Ex d Ⅱ C T6 Gb Protection level: IP65
