Description: Product adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensors, the products with good reliability, high precision and interchangeability. Adopt RS485 hardware interface (with the protection design), the protocol layer compatible with standard industrial Modbus RTU protocol.This product integrating MODBUS protocol and ordinary UART communication protocol, users can choose communication protocols, UART communication support automatic report function (Connect the RS485 serial interface mode tool by automatically output temperature and humidity).Using Steps: 1.Connect 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 precision. 5.Industrial products, high progress SHT20 temperature and humidity sensor, the RS485 communication. 6.Standard MODBUS protocol and ordinary protocol, the user can choose communication protocol. 7.Baud rate can decide for themselves. 8.General agreement with automatic upload function, upload speed can decide for themselvesParameters:1.Product Name:Modbus RTU RS485 SHT20 Temperature Humidity Transmitter2.Working Voltage:DC 5V~30V3.Output signal:RS485 signal4.Communication protocol:Modbus RTU and ordinary protocol5.Communication address:1~247(default 1)6.Temperature Range:-40~607.Temperature Precision:+/-0.58.Temperature Resolution:0.19.Humidity Range:0%RH~80%RH10.Humidity Precision:+/-3%RH11.Humidity Resolution:0.1%RH12.: less than 0.2W13.Work Temperature:-40~8515.Work Humidity:0%~95%RH16.Size:65 * 46 * 28.5mmCondition: NewType: Logic ICsDissipation : less than 0.2Wcolor: Whitematerial: plasticApplication: Temperature Humidity TransmitterFeature: RS485 supports 1000 meters communicationApplication:1.Factory Detect2.Equipment box Detect3.Environmental test4.Home securityPackage Contents:1pcs * Temperature and humidity sensorOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
