NDIR Carbon Dioxide CO2 Sensor Module MH-Z14A Serial Port PWM Analog Output 0-5000ppm

Description: MH-Z14A CO2 gas sensor is a general intelligent small sensor, using the non-dispersive infrared (NDIR) principle to detect carbon dioxide in , and has a good selectivity and no oxygen dependence, long service life.It has built-in temperature compensation, as well as digital output, analog output and PWM output, convenient to use.This is a high-performance sensor combined with infrared absorption gas detecting technology, optical path design, excellent circuit design. Features: Gas chamber adopts gold plating processing, waterproof and anti-corrosion, long service life. High sensitivity, low power consumption, excellent stability, resistant to moisture. Temperature compensation, remarkable linear output(the more CO2, the higher voltage). It provides a serial port (UART), analog (DAC) and PWM waveform output. Widely used for heating and refrigeration equipment, purification equipment, quality monitoring equipment, fresh system at smart home and school. Specifications: Working Voltage: DC4-6V Working Current: 50mA (average); 100mA(peak) Detection Range: 0-5000ppm Accuracy: ±50ppm Preheat Time: 180S Analog Output Voltage: 0.4-2V (linear output) Digital Output: Serial data output (9600, N, 8, 1) Response Time: ≤30S Operating Temperature: 0~60℃ Operating Humidity: 0~90%RH Storage Temperature: -20~60℃ Size: 5.7*3.5*1.5cm/2.24*1.38*0.59in Package Includes: 1 x Carbon Dioxide Sensor 1 x Cable
