Temperature & Humidity Sensor FS00101 Introduction

The FS00101 temperature and humidity sensor is compact in size and has a built-in sensor probe. The circuit uses an industrial-grade microprocessor chip and a high-precision temperature sensor to ensure excellent reliability and high accuracy.

This product uses the 485 communication interface standard ModBus-RTU communication protocol, with communication address and multiple baud rates that can be set, and the maximum communication distance is up to 2000 meters.

Temperature & Humidity Sensor FS00101 Features

485 communication interface with a standard Modbus-RTU protocol, and supports adjustable communication address and baud rate.


This sensor allows for the longest possible communication line to be up to 2000 meters.


It has high accuracy and low drift, with temperature accuracy of ±0.5℃ and humidity accuracy of ±4%RH.


It is equipped with dedicated EMC anti-interference components that allow it to withstand strong electromagnetic interference in the field. The industrial-grade processing chip gives the sensor a wide range of applications.


The sensor can operate normally within a wide voltage range of 10~30V, even when being powered by centralized power supply from a remote location.
