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: A few hints... - 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, with some unexpected behavior - 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. ## Features - industrial universal standard RS485 bus MODBUS-RTU protocol interface - PLC and DCS for monitoring - Temperature measurement range -30°C~80°C - Humidity measurement range 0~100%RH - Humidity measurement accuracy ±3%RH @25°C ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZYVZZKK | | Batteries Required? | No | | Batteries included? | No | | Customer Reviews | 4.5 4.5 out of 5 stars (30) | | Date First Available | 4 Nov. 2019 | | Item Package Quantity | 1 | | Item Weight | 82 g | | Item model number | Tdrs485sht30probe | | Manufacturer | Taidacent | | Part number | Tdrs485sht30probe | | Product Dimensions | 8 x 1 x 1 cm; 82 g | ## Images ![Taidacent SHT30 RS485 Modbus RTU Temperature and Humidity Sensor Transmitter for PLC and DCS Room Thermocouple Monitoring - Image 1](https://m.media-amazon.com/images/I/51n2ozn6f0L.jpg) ![Taidacent SHT30 RS485 Modbus RTU Temperature and Humidity Sensor Transmitter for PLC and DCS Room Thermocouple Monitoring - Image 2](https://m.media-amazon.com/images/I/51G4JJv3brL.jpg) ![Taidacent SHT30 RS485 Modbus RTU Temperature and Humidity Sensor Transmitter for PLC and DCS Room Thermocouple Monitoring - Image 3](https://m.media-amazon.com/images/I/51bt-0htRQL.jpg) ![Taidacent SHT30 RS485 Modbus RTU Temperature and Humidity Sensor Transmitter for PLC and DCS Room Thermocouple Monitoring - Image 4](https://m.media-amazon.com/images/I/51P2D91Y2gL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A few hints... *by K***N on 19 March 2022* 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. ### ⭐⭐⭐⭐ Works fine, with some unexpected behavior *by P***R on 4 April 2024* 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. ### ⭐⭐⭐⭐⭐ Works as expected *by T***S on 16 January 2024* 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. ## Frequently Bought Together - Taidacent SHT30 RS485 Modbus RTU Temperature and Humidity Sensor Transmitter for PLC and DCS Room Thermocouple Monitoring - USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection - HiLetgo RS485 SHT20 Temperature Humidity Sensor Module High Precision Temperature Humidity Monitor Transmitter Sensor Probe Compatible to Modbus with 1M Lead --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/400801417-taidacent-sht30-rs485-modbus-rtu-temperature-and-humidity-sensor-transmitter](https://www.desertcart.sk/products/400801417-taidacent-sht30-rs485-modbus-rtu-temperature-and-humidity-sensor-transmitter) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-01*
