MH-441D Methane Gas Sensor Introduction: The MH-441D methane gas sensor is a universal intelligent infrared gas sensor (hereinafter referred to as the sensor) that uses the principle of non dispersive infrared (NDIR) to detect methane gas present in the air, with good selectivity and no oxygen dependence; 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. Convenient to use, it can be directly used as a substitute for catalytic combustion components and is widely used in various situations where methane and explosive gases exist. Mainly used in: HVAC refrigeration and indoor air quality monitoring, industrial process and safety protection monitoring, agricultural and livestock production process 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. It is resistant to water vapor interference and not toxic, and can directly replace the catalytic combustion principle sensor Technical parameters: Product model: MH-441D Detection gas: methane Working voltage: 3.6-5 V DC (powered by safety barrier) Average current:<85 mA Measurement range: optional within the range of 0-10% Vol (see Table 2 for details) Interface level: 3.0V Output signal: UART 0.4-2 V (requires output through safety barriers) Preheating time: 3 minutes Response time: T90 ＜ 30 s Working temperature: -20~60 ℃ Working humidity: 0-95% RH (without condensation) Overall dimensions: Φ twenty × 22.4mm Weight: 35 g Service life:>5 years Protection level: IP54 Power and communication terminals Intrinsic safety parameters: Ui=7.5VDC, Ii=265mA, Pi=0.5W, Ci=10 μ F. Li=0mH
