KCS540 is a gas detection module based on the principle of NDIR infrared absorption, which is suitable for detecting the concentration of carbon dioxide in a gaseous environment at room temperature.
KCS540 adopts a patented optical cavity, imported light source and dual-channel detector to achieve dual optical path reference compensation in space. KCS540 has good selectivity, no oxygen dependence and long life.
KCS540 has UART, IEC digital output, analog voltage output and PWM frequency output mode, which is convenient for customers to choose the application; The KCS540 provides zero calibration, sensitivity calibration, and clean air calibration commands, and provides customers with a manually calibrated MCDL pin to facilitate the relative zero calibration of the sensor module using outdoor free-flowing clean air. KCS540 adopts diffusion ventilation method, which has a fast diffusion speed.
KCS540 can be widely used in HVAC fresh air control, indoor air quality monitoring, agricultural and animal husbandry production process monitoring, can be installed in intelligent buildings, ventilation systems, robots, automobiles and other applications. It can also be applied to other confined spaces for air quality monitoring.
