Temperature Humidity Transmitter Rs485 Sht20 Sensor Modbus Rtu Acquisition Module Transducer High Product adopts industrial-grade chip, high- SHT20 temperature and humidity sensors, the products with good reliability, high and interchangeability. Adopt RS485 hardware interface (with the protection design), the protocol layer with standard industrial Modbus RTU protocol. This product integrating MODBUS protocol and ordinary UART communication protocol, users can communication protocols, UART communication support automatic report function ( the RS485 serial interface mode tool by automatically output temperature and humidity). Using Steps: 1. signal receiver such as for to RS485 terminal.2.Input supply at terminal. 3.According to the acquired data, the data is processed differently according to actual needs. Note: 1.Users need to prepare their own ModBus debugging tool and RS485 debugger. 2.Users needs to complete write code according to the communication protocol and commands if using the controller to receive data. Features: 1.Support MODBUS RTU protocol. 2.RS485 supports 1000 meters communication. 3.Standard DIN35 mounting rails. 4.High . 5.Industrial products, high SHT20 temperature and humidity sensor, the RS485 communication. 6.Standard MODBUS protocol and ordinary protocol, the user can communication protocol. 7.Baud rate can decide for themselves. 8.General agreement with automatic upload function, upload speed can decide for themselves Parameters: 1.Product Name:Modbus RTU RS485 SHT20 Temperature Humidity Transmitter 2.Working Voltage:DC 5V~30V 3.Output signal:RS485 signal 4.Communication protocol:Modbus RTU and ordinary protocol 5.Communication address:1~247(default 1) 6.Temperature Range:-40~60 7.Temperature :+/-0.5 8.Temperature Resolution:0.1 9.Humidity Range:0%RH~80%RH 10.Humidity :+/-3%RH 11.Humidity Resolution:0.1%RH 12.: less than 0.2W 13.Work Temperature:-40~85 15.Work Humidity:0%~95%RH 16.Size:65 * 46 * 28.5mm Condition: New Type: Logic ICs Dissipation : less than 0.2W color: White material: plastic Application: Temperature Humidity Transmitter Feature: RS485 supports 1000 meters communication Application: 1.Factory Detect 2.Equipment box Detect 3.Environmental test 4.Home security Package Contents: 1pcs * Temperature and humidity sensor Only the above package content, other products are not included.
