TSH300: MODBUS Temperature and Humidity Sensor

TSH300 is an RS-485 humidity and temperature sensor. The device does not require an external power supply. It is powered via the interface. The sensor is an excellent solution for humidity and temperature measurement. The humidity and temperature sensor integrates basic elements and signal processing and provides a fully calibrated digital output. This results in superior measurement quality. It focuses on applications requiring precise humidity and temperature monitoring - server rooms, offices, food and grocery stores, etc. It is also suitable for smart office applications. TSH300 widely supports the Modbus RTU Modbus (BMS) protocol and Industrial Automation Systems (IAS). Each sensor has a unique serial code, which allows multi-sensor support on the same RS-485 bus. The RS-485 humidity and temperature sensor uses two RJ45 connectors for easy daisy-chain wiring. Standard UTP / FTP patch LAN cable can be used for interconnection between sensors and the controller. A special accessory, which allows easy installation on 19" cabinets, can be ordered separately.
