Carbon Monoxide CO Sensor Modbus RS485

The RS485 Carbon Monoxide (CO) Sensor is a compact, wall-mounted sensor that measures CO concentrations from 0 to 2,000 ppm - with a resolution of 10 ppm - while also providing calibrated temperature data. In addition, integrated temperature compensation and low baseline drift help maintain stable readings under changing conditions. Moreover, its T90 response time of less than 35 seconds enables timely detection of concentration changes.

For easy integration, it supports RS485 Modbus RTU communication and operates on a 5–28 V DC power supply. The sensor features linear output, integrated temperature compensation, low baseline drift, low power consumption, surge-protected communication, and an expected operating life of at least two years in air.

It is compatible with SenseCAP LoRaWAN Data Logger to connect with the LoRaWAN network for low-power and long-range wireless communication.
