User Manual : USR-SENS-WSD


USR-SENS-WSD temperature and humidity data acquisition module has optional RS485 / RS232 / TTL level output and MODBUS control protocol,which allows multiple modules connected to the bus network, and build network with equipment in accordance with the MODBUS protocol , to monitor Production site environment changes.


  • DATA/VCC/GND/RXD(RS85-A)/TXD(RS485-B)interface, simple and reliable, easy to expand
  • RS232/RS485/TTL signal transmitted methods
  • Data transmission based on MODBUS Industrial control protocol, Reliable performance, good compatibility, easy to network
  • Support simple character instruction, single module easily used in simple applications
  • Small size, easily installed
  • Moisture-proof handling, suitable for damp environment as greenhouse
  • Serial port configuration parameters:
  • Baud rate: 1200 / 4800 / 9600 / 19200 / 38400 / 57600;
  • Data bits: 8;
  • Parity: No / Odd / Even;
  • Stop bit: 1 /2;
  • Interrupt the power and restart, the configuration takes effect
  • Support data formats: serial MODBUS protocol, Simple ASCII character instruction: “READ”, “AUTO”, “STOP”
  • The module ID can be configured, Range:1~247
