Swiss SENSIRION imported temperature and humidity sensor SHT10, the sensor acquisition of high precision, good consistency, accuracy is guaranteed! Industrial design ideas, wide voltage DC9~30V input; module acquisition of temperature and humidity signal data, through the RS485 interface output; module using Modbus-RTU communication, can be adapted to PLC, DCS and a variety of configuration software
A. Summary
MB1TH 1Road surface humidity acquisition module, the Swiss imports of SENSIRION temperature and humidity sensor SHT10/11, the sensor with high acquisition accuracy and good consistency; temperature and humidity data acquisition module signal to the output through a RS485 interface module; using Modbus-RTU communication, can be adapted to PLC, DCS and a variety of configuration software.
Through the software can set the alarm value of the temperature and humidity module, such as the emergence of an emergency problem can prompt the user to deal with the problem and locate the position of the alarm module. The user can set the alarm value of the upper and lower limits of temperature and humidity, and the temperature and humidity limit alarm function can be opened or closed separately.
Can be used for cold storage temperature and humidity data acquisition, vegetable greenhouses, animal breeding, industrial environment monitoring, barn temperature and humidity monitoring, a variety of environmental temperature data acquisition and control, etc..
Two. Characteristic
1. Swiss SENSIRION imported temperature and humidity sensor SHT10, high precision, good consistency.
2. Increase the temperature and humidity on the lower limit alarm function to facilitate the user to deal with the problem, and locate the fault location.
Three Using standard Modbus-RTU protocol, can be adapted to PLC, DCS and a variety of configuration software, etc..
4. Communication protection: RS485 communication signal output interface using overvoltage and over current dual protection.
Five Temperature and humidity out of limit alarm, temperature and humidity limit alarm, communication format can be set through the software.
Six Power polarity protection.

Four. Product appearance
Five. Module indicator lamp and switch function specification
1. POW/SET;Module working status indication
A.Green light: the module works in the running state. B. red light: the module has the configuration parameters have been written, need to re power up.
2. TXD/RXD:Communication status indication
A.The green light flashes: the communication receives the data B. red light flashes: the module is sending data
C.The green light is always on: DATA+ and DATA- on the communication line RS485 line is connected to the reverse or the connection is broken.
Three Internal upper left corner reset switch
A. When the communication parameters (module address, baud rate, parity bit) do not know or communication parameter misspecification, and can not establish contact module communication, the solution is to reset the communication parameters; we use the clip to hold the reset switch is not open, 5 seconds after the [POW/SET] module of the red indicator lights, release the reset switch, the communication the parameters have been reset, as long as the power supply module after the restart time, the communication parameters of the module has been reset.
B. Communication parameters after reset: Address: 1, baud rate: 9600bps, parity: No.
