SHT20 RS485 Temperatur- und Feuchtigkeitssender-Sensormodul Digitale hochpräzise industrielle Modbus-Rtu-Protokollüberwachung

Produktbeschreibung

Product introduction
The product uses industrial-grade chips and high-precision imported SHT20 temperature and humidity sensors to ensure the excellent reliability, high precision and interchangeability of the product. Using RS485 hardware interface (with lightning protection design), the protocol layer is compatible with the standard industrial Modbus-Rtu protocol. This product integrates the MODBUS protocol and the common protocol. The user can choose the communication protocol by himself. The common protocol has an automatic upload function (connecting RS485 and passing the serial port adjustment tool will automatically output temperature and humidity).
