INSTRUMENT DESCRIPTION
General description
The Humidity and Temperature sensor adopt high quality digital
sensors, with reliable performance, high precision, small year
drift, fast response. It is suitable for temperature and humidity
measurement of communication rooms, offices, workshops,
warehouses, hospitals, HVAC, and building automation etc..
The Relative Humidity and the Temperature measurements can be
read through the RS485 Modbus RTU communications port.
The sensor can be mounted horizontally (on the ceiling) or verti-
cally (on the wall) using 2 screws or a DIN rail. The connections
are really easy: only 4 wires to complete the installation.
