Wsht20 Industrial Temperature Humidity Sensor RS485 High Precision Monitor Automatic Output Version

Description:
There are two versions, automatic output version and version for MODBUS. The automatic output version is connected to RS485, and temperature and humidity will be automatically output through serial port adjustment tool. The version for MODBUS outputs temperature and humidity through a host computer or PLC equipment. Free test PC configuration software is provided for MODBUS version!

The product uses industrial-grade chips and high-precision temperature and humidity probes to ensure 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 protocol for Modbus-Rtu.
