## Overview

The Taidacent SHT30 RS485 Modbus RTU sensor delivers industrial-grade temperature and humidity monitoring with a wide -30°C to 80°C range and 0-100% RH measurement. Featuring a universal RS485 Modbus-RTU interface, it integrates effortlessly with PLC and DCS systems, ensuring high accuracy (±0.5°C, ±3% RH) and long-term stability. Its compact design and customizable communication options make it the go-to choice for professional-grade environmental control.

## Description

The probe adopts the industrial universal standard RS485 bus MODBUS-RTU protocol interface, which is convenient for accessing various instruments or systems such as PLC and DCS for monitoring the state quantity such as temperature and humidity. A high-precision sensing core and related devices are used internally to ensure high reliability and excellent long-term stability. RS232, RS485, CAN, 4-20mA, DC0~5V\10V, ZIGBEE, and Lora can be customized. , WIFI, GPRS, NB-IOT and other output methods.Temperature measurement range -30°C~80°C Temperature measurement accuracy ±0.5°C @25°C Humidity measurement range 0~100%RH Humidity measurement accuracy ±3%RH @25°C Communication interface RS485 Default baud rate 9600 8 n 1 Power supply DC6~24V 1A Operating environment temperature -40~80°C Operating environment humidity 5%RH~90%RH

Review: Excellent for price. n = no parity. My PLC only allows 400001 as starting address, where the instructions said 40001. However, when I entered 400001 it did not matter, it gave me the results. Don't forget to divide the numbers by 100 to get the correct temperature and % humidity. Convert from Deg C to Deg F by multiplying by 1.8 and adding 32. I also forgot to hook up the red wire. It works fine with 24 VDC.
Review: Excellent product. Very accurate. Only reason that I did not give it 5 stars is that I could not set the baud rate. The documentation about baud rates has errors. Address 66 and 67 are referenced as baud rate. The write register example reads the register. If 9600 baud is fast enough, this product works fine.

It connected right up to my USB-to-RS485 interface, and my PC could read it right away using python's pymodbus module. Value agrees with other temperature sensors.
