In case, you connect 2 SHT20, make sure you update the access number so both devices are polled by the modbus master. I also contacted the support team which was very quick to answer and provide the answer. The support team also took into account that the documentation was only in chinese ( used Google translate) and will look at an english version which is very positive. ## Features - RS485 SHT20 Temperature Humidity Sensor Module - High Precision Temperature Humidity Monitor Sensor - Industrial-grade chip and high precision temperature and humidity probe to ensure the excellent reliability - RS485 hardware interface (with lightning protection design), the protocol layer compatibility standard industry Modbus protocol. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Hailege | | Part number | H-1-1591 | | Item Weight | 30 g | | Package Dimensions | 10.5 x 7.4 x 3.6 cm; 30 g | | Manufacturer reference | H-1-1591 | | Batteries included? | No | | Batteries Required? | No | ## Images ![Hailege RS485 SHT20 Temperature Humidity Sensor Module High Precision Temperature Humidity Monitor Transmitter Sensor Probe Compatible to Modbus with 1M Lead - Image 1](https://m.media-amazon.com/images/I/51N9OgH-dSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product and customizable and great support team *by M***L on 10 December 2025* Great kit and easy to configure.
