Product Overview

The IBI-TH485 temperature and humidity sensor is designed based on the RS-485 communicationinterface, compatible with the standard Modbus-RTU protocol, and can be connected to the Modbus network to achieve temperature and humidity measurement and monitoring.


The IBI-TH485 sensitive element uses SHT30, a newly designed CMOSens chip, an improvedcapacitive humidity sensor element and a standard energy gap temperature sensor element. Its performance has been greatly improved or even exceeds the previous generation of sensors (SHT1x and SHT7x). ) Reliability level to make its performance in high humidity environments more stable.

IBI-TH485 adopts the DIP switch to set the address, which avoids the need to set the address with the upper computer in advance. It is simple and convenient to maintain and replace.

IBI-TH485 has excellent long-term stability, low latency, low power consumption, strong resistance to chemical pollution and excellent repeatability. It is used for accurate temperature & humidity relative measurement in HVAC, communication equipment rooms, warehouse buildings, and automatic control applications. The ideal solution for humidity.
