Description
Description: Product adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensors, ensure the products with good reliability, high precision and interchangeability.Adopt RS485 hardware interface (with the lightnings protection design), the protocol layer compatible with standard industrial Modbus Rtu protocol.This product integrating MODBUS protocol with ordinary, users can choose communication protocols, common agreement with automatic upload function(Connect the RS485 serial interface mode tool by automatically output temperature and humidity).Features: Industrial products, high progress SHT20 temperature and humidity sensor, the RS485 communication;Standard MODBUS protocol with ordinary at an organic whole, the user can choose communication protocol;Baud rate can decide for themselves;General agreement with automatic upload function, upload speed can decide for themselves. Product Parameters: Work voltage: DC4-30V (highest do not exceed 33 V) Most powerful: 0.2 W Work environment: Temperature 20 ? - 60 ?, Humidity 0-100%RHControl precision: Temperature±0.3?, Humidity ±3%RHOutput interface: RS485 communication (standard MODBUS protocol and custom ordinary), see note agreement device.Device address: 1-247 can be set, the default is 1.Baud rate: 9600(the user can set), 8bits, one stop, no check;Shape size: 60*30*18mm MODBUS PROTOCAL: Modbus Function Code:0x03: Read keep register0x04: Read input register0x06: Write a single keep register0x10: Write more keep registers
Package included:
1 x SHT20 temperature and humidity sensor
