## 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: Works fine, you just have to poll function code 03 (holding registers) and the transducer I received had slave address 01. Temperature is located at register 1 (address 0) and humidity is register 2 (address 1). IMPORTANT I found that if you poll more than 2 registers in one message, the transducer seems to go into an 'auto broadcast' mode, where it automatically transmitts on a 1-2 second interval. This gave me a bit of a headache.

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.
