MH-Z19C IR Infrared CO2 Sensor Module Carbon Dioxide Gas Sensor

The MH-Z19C Carbon Dioxide Sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor that uses the principle of non-dispersive infrared radiation (NDIR) to detect the presence of C02 in the air. Built-in temperature compensation: simultaneously has serial output, PWM output, easy to use. The sensor is a high-performance sensor created by closely combining proven infrared absorption gas detection technology with sophisticated optical design and sophisticated circuit design. Product Parameters: Detection gas: carbon dioxide Power supply voltage: DC (5.0±0.1)V Average current: <40mA (with 5V power supply) Peak current: 125 to (5V power supply) Interface level: 3.3V (compatible with 5V) Measuring range: 400-5000PPM optional Output signal: Serial UART (TL level 3.3V) Warm-up time: 1 minute Response time: T90<120s Operating temperature: -10-50 degrees Operating Humidity: 0~95% RH (non-condensing)
