MH-V1512A Carbon Dioxide Gas Sensor Introduction: The MH-V1512A carbon dioxide gas sensor (hereinafter referred to as the sensor) is a universal and small sensor that utilizes the principle of non dispersive infrared (NDIR) to detect the presence of CO2 in the air. It has good selectivity, no oxygen dependence, long lifespan, built-in temperature compensation, and digital output and PWM output, making it easy to use. This sensor is a high-performance sensor that combines mature infrared absorption gas detection technology with precise optical path design and sophisticated circuit design. Features: 1. The air chamber adopts electroplating treatment, which is waterproof and corrosion-resistant. 2. Provide output methods such as serial port (UART) and PWM waveform. 3. It is resistant to water vapor interference, not toxic, and has a long service life. Technical parameters: Product model: MH-V1512A Detection gas: carbon dioxide Power supply voltage: DC (5.0 ± 0.1) V Average current:<40mA (@ 5V power supply) Peak current: 125 mA (@ 5V power supply) Interface level: 3.3V (compatible with 5V) Measurement range: optional within the range of 400~10000ppm (see Table 2 for details) Output signal: Serial port (UART) (TTL level 3.3V) PWM Preheating time: 10s Response time: T90<60s Working temperature: -30 ℃~85 ℃ Working humidity: 0-95% RH (without condensation) Storage temperature: -40 ℃~95 ℃ Weight: 7 g Life:>10 years
