Temperature Humidity Acquisition

Temperature Humidity Acquisition and Transmission

Module,Supports TTL/RS232/RS485 Interface [USR-SENS-WSD]

Temperature and humidity data acquisition module has optional RS485 / RS232 / TTL level output and MODBUS control protocol.

Temperature Humidity Acquisition USR-SENS-WSD temperature and humidity data acquisition module is of high performance. With optional RS485 / RS232 / TTL different level output and MODBUS industrial control bus protocol, it 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 in time and steadily. So that users can accurately grasp the changes of different applied field and act quickly to guarantee the stability of the production site environment.
