The temperature and humidity sensor chip for imported sensor has exnt stability, consistency, using the RS485 interface, enabling simultaneous multi-point monitoring, networking and remote-site digital display functions, RS485 interface mode, use the industry widely used Modbus data communication protocol for data communication can be used with all types of control equipment, instrumentation and computer display connected directly.
This temperature and humidity sensors for the RS-485 bus temperature and humidity sensor, RS485 interface, can achieve more while monitoring, networking and remote-site digital display.1. CommunicationThis product uses the RS485 interface mode, using a wide range of industrial applications Modbus data communication protocol for data communication can be used with all types of control equipment, instrumentation and computer display connected directly.2. Remote FunctionThe RS485 interface, the maximum transmission distance of 1200 m. Enables remote temperature and humidity monitoring and control.3. Networking featuresThis sensor is connected by multiple bus serial, external power supply is required for each sensor separately, bus endpoint digital with computer serial port connection. It can be achieved to receive the device-centric multi-point monitoring, in order to achieve a wide range of centralized control and management. The same network can monitor up to 32 monitoring points.5.Scene showsThis large display both temperature and humidity sensors, can be directly observed the scene through the display panel changes in temperature and humidity
