## Description

Specifications: Working Voltage: DC 5V~30V Output signal:RS485 signal Communication protocol: Modbus RTU and ordinary protocol Communication address: 1~247(default 1) Temperature Range: -40℃~60℃ Temperature Precision: +/-0.5℃ Temperature Resolution: 0.1℃ Humidity Range: 0%RH~80%RH Humidity Precision: +/-3%RH Humidity Resolution: 0.1%RH Power: .Support MODBUS RTU protocol. 2>.RS485 supports 1000 meters communication. 3>.Standard DIN35 mounting rails. 4>.High precision. 5>.Industrial products, high progress SHT20 temperature and humidity sensor, the RS485 communication. 6>.Standard MODBUS protocol and ordinary protocol, the user can choose communication protocol. 7>.Baud rate can decide for themselves. 8>.General agreement with automatic upload function, upload speed can decide for themselves..9>.This product integrating MODBUS protocol and ordinary UART communication protocol, users can choose communication protocols, UART communication support automatic report function (Connect the RS485 serial interface mode tool by automatically output temperature and humidity). Package Includes: 1x Temperature Humidity Transmitter Note: 1>.Please allow 1-2cm error due to manual measurement. Thanks for your understanding. 2>.Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.

Review: Works as expected - I've now got five of these and they appear to work well. The removable plug is convenient and there's the additional bonus that they are designed to be mounted on a DIN rail so a neat fixing can be obtained.
Review: Did not work - I have tried and tried to get this product working. First, it has no proper instructions detailing the Modbus address configuration. Second, even when I did find this from another manufacturer, the device didn't respond. I then opened it up and could see no TX and RX lights flashing when communications were in progress. In short, a big waste of time and money.

## Features

- Note: Users need to prepare their own ModBus debugging tool and RS485 debugger. Users needs to complete write code according to the communication protocol and commands if using the controller to receive data.
- Using Steps: 1>.Connect signal receiver such as Arduino to RS485 terminal. 2>.Input power supply at power terminal. 3>.According to the acquired data, the data is processed differently according to actual needs.
- Product adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensors, ensure the products with good reliability, high precision and interchangeability.
- Adopt RS485 hardware interface (with the lightning protection design), the protocol layer compatible with standard industrial Modbus RTU protocol.
- QUALITY ASSURANCE: To provide you with the highest quality assurance, if you are not satisfied with the product, please contact us.

### ⭐⭐⭐⭐⭐ Great Value Sensor
*by D***T on 8 March 2020*

Perfect temperature/Humidity sensor that can be communicated either via modus or ascii. If you want to use more than one you will need to use modus as you cannot address more than one with plain text. Can be calibrated (will need to be!). Very flexable with input voltage. Was used with a Crestron Controller but also on a PC for setup and testing.
