RS485 Carbon Monoxide CO Sensor: Modbus RTU, Air Quality Monitoring, Carbon Monoxide and Temperature

The RS485 Carbon Monoxide (CO) Sensor is a compact, wall-mounted sensor designed for industrial, environmental, smart-home air-quality, and laboratory monitoring. It measures CO concentrations from 0 to 2,000 ppm while also providing calibrated temperature data. In addition, integrated temperature compensation and low baseline drift help maintain stable readings under changing conditions. For easy integration, it supports RS485 Modbus RTU communication and operates on a 5–28 V DC power supply. Moreover, its low-power design, reverse-polarity protection, and built-in surge, TVS, and ESD protection ensure reliable long-term use.
