Parameter Temperature measuring range -30℃~80℃ Temperature measuring accuracy ±0.5℃ @25℃ Humidity measuring range 0~100%RH Humidity accuracy ±3%RH @25℃ Communication Interface RS485 Default baud rate 9600 8 n 1 Power DC6~24V 1A Running temperature -40~80°C Working humidity 5%RH~90%RH Wiring methods Yellow A+ RS485A+ Blue B- RS485B- Green GND Power- Red VIN Power+ 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 | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 31 Reviews | ## 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 March 19, 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 April 4, 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 January 16, 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.gr/products/167232944-taidacent-sht30-rs485-modbus-rtu-temperature-and-humidity-sensor-transmitter](https://www.desertcart.gr/products/167232944-taidacent-sht30-rs485-modbus-rtu-temperature-and-humidity-sensor-transmitter) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-30*
