SHT20 Temperature and Humidity Sensor RS485 Communication

-40C /125C Thermometer Heat Air Conditioner Thermostat Medical Smart Home Industrial Warehouse Laboratory Greenhouse Hotel Hospital Modbus Rtu Protocol

     It is a temperature and humidity sensor using the Sht20 sensor and communicating over rs485. Communication with the sensor is done over rs485 with the modbus rtu protocol. You can communicate over distances up to 1000 meters. The sensor can be used with microcontroller kits such as Arduino, esp32 etc.

     It is connected to the device with a Usb Rs485 converter. You can use one of the methods in the software support below. Basically, heat temperature reading commands can be sent through the memory of the device. Address change and other setting commands can be sent. This can be done by sending hex codes over the terminal. You can also do it with Pc software.
