Description of XY-MD02 Temperature Humidity Transmitter Module with SHT20 Sensor - High-Performance Temperature Humidity Sensor Module

❤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. ❤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).

Simple Yet Effective Solution for Climate Control

This temperature and humidity transmitter was just what I needed to accurately monitor the climate in my home. The installation was easy and the device works seamlessly with my other Tools and Home Improvement accessories. Based on my observations, it provides very precise readings and is a fantastic tool to have for maintaining a comfortable environment. However, the device could benefit from a more user-friendly interface for changing the settings.

Pros
  • Accurately measures temperature and humidity levels in real-time
Cons
  • Requires additional equipment to integrate data into a larger system

Simple and easy to use

A quick google search will find the product manual. There's nothing special about it, but there's nothing special about this device. You simply turn it on and communicate with it via RS-485 Modbus RTU.

Pros
  • Household Appliances
Cons
  • Expensive

Poor accuracy makes it useless

Would like to like this device. Well put together and Modbus works as advertised. Unfortunately it doesn't seem to be calibrated. Humidity 25%, actually 43%. Read 98 F (37 C) when actually 73. Bought 2 of these and haven't tracked reality or each other. They offer a calibration register to set +/- 10°C and +/- 10% humidity, but this is not enough to correct the error and with an error that large, don't trust that Device provides calibrated readings.

Pros
  • Accessories
Cons
  • Good but not great
