506-97 warehouse environment monitoring room temperature and humidity sensors 485 Interface modbus RTU

Outline


DB506 temperature and humidity sensor for the RS-485 bus-type temperature and humidity sensors, with RS485 interface, can achieve more while monitoring, networking and remote, on-site digital display. DB506 temperature and humidity sensors both large display, temperature and humidity changes can be directly observed the scene through the display panel. The product is mainly used in indoor temperature and humidity measurements, can be widely used in subway, shopping malls, hospitals, stations, terminals, libraries, museums, workshops, sports stadiums and other public places, as well as building automation, food storage and various other needs to be measured indoor temperature and humidity of the occasion.
