Carbon dioxide sensor KCS503

CO2NDIRoptical

KCS503 is a gas detection module based on the principle of NDIR infrared absorption, suitable for detecting the concentration of carbon dioxide in a gaseous environment at room temperature. KCS503 adopts a patented optical cavity, imported light source and dual-channel detector to realize the reference compensation of dual optical paths in space. KCS503 has good selectivity, no oxygen dependence and long life. KCS503 has UART, 485 output and 4-20mA current output (or analog voltage output) to facilitate customer selection of applications; The KCS503 provides zero point calibration, sensitivity calibration and clean air calibration commands, and provides a manually calibrated MCDL pin for customers to perform relative zero calibration of sensor modules using outdoor free-flowing clean air. KCS503 adopts convection diffusion ventilation method, and the diffusion speed is fast. KCS503 is designed for CO2 concentration measurement in high humidity environments such as mushroom rooms, incubation rooms, and agricultural greenhouses. It can also 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, can also be applied to other narrow space air quality monitoring.
