KCS501X is a gas detection module based on the principle of NDIR infrared absorption, suitable for detecting carbon dioxide concentration in gas environment at room temperature.
KCS501X adopts a patented optical cavity, imported light source and dual-channel detector to achieve dual optical path reference compensation in space. KCS501X has good selectivity, no oxygen dependence, and long life.
KCS501X has UART, IIC digital output, analog voltage output and PWM frequency output mode, which is convenient for customers to choose applications; The KCS501X 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. KCS501X adopts diffusion ventilation method, which has a fast diffusion speed.
KCS501X 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.

5. Installation instructions
The sensor is mounted with a positioning hole spacing of 44.5mand a mounting hole diameter of 2.8 mm
The wiring socket spacing is 2.54 m m
Note: SW400PV3.01, mounting aperture: 3.2mm
6. Matters that should be paid attention to in maintenance
The sensor should be calibrated regularly, it is recommended that it be no more than 3 months, and calibration is not required on the long-term operation side if automatic calibration is turned on
Do not use the sensor for a long time in an environment with a high density of dust
Please use the sensor within the range of the sensor's power supply
In order to be able to purchase the specific specifications required, please provide the following information
1) Sensor name
2) Sensor range
3) Sensor measurement accuracy such as SW400, 0-2000pp
