CO2 gas sensor CM1107NS

NDIRinfraredfor air quality monitoring

CM1107NS is a dual beam (single light source, dual channel) NDIR CO 2 sensor, based on non-dispersive infrared (NDIR) technology, which can detect CO 2 concentration of indoor air. With higher accuracy, superior long term stability, it is widely used for ventilation system, air purifier, air conditioner, intelligent agriculture, storage and cold-chain, etc Features - NDIR technology with independent intellectual property - Dual beam detection for superior stability and better accuracy - High accuracy, long term stability, long lifespan (>10years) - Wide range measurement range 0-10000ppm - Temperature calibration within whole measurement range - Signal output PWM/UART/I 2 C - Small size and compact structure, easy to install Specifications - Response time - ≤30s - Accuracy - ±(30ppm+3% ofreading) (0-5000ppm, -10℃-50℃, 50±10%RH） - Working temperature - -10℃~50℃ - Working humidity - 0~95% RH（non-condensing） - Power supply - DC 4.5V-5.5V; ripplewave ＜50mV - Working current Average - ＜50mA@1s - Signal output - UART_TTL (3.3V/5V electrical level), PWM, I²C(3.3V electrical level) - Dimension - W33*H21.7*D12.7（mm）(without pin) - Weight - 6.3g
