Humidity sensor WS-2	ACTIVE	51

General usage conditions - for industrial and commercial usage in conditions of high humidity (0-95%, non-condensing). The device is not intended for domestic use.

A humidity sensor WS-2 is designed to measure air humidity indoors. It is manufactured as a board, installed into a plastic cover.

An air relative humidity sensor is connected to the following NetPing 2/PWR-220 power distribution units (PDUs). The information about connecting a digital humidity sensor is in the document “User Guide” for NetPing PDU, to which they are connected. The information about a sensor configuration is in the document “Firmware Description” for NetPing power distribution unit, to which you are connecting a humidity sensor.

It is possible to plug only one humidity sensor WS-2 to one NetPing PDU.

A loop of a sensor consists of 4 wires that transmit a digital information about a humidity and a temperature. The loop is connected inseparably to a sensor and is 2 meters long. If necessary, it is possible to make a loop sensor longer up to 10 meters using RC-4 sensor loop extender plugged one into another.

A humidity sensor is constructed based on the chip HIH6031-021.

See more detailed information about a relative air humidity in the article: Relative humidity.
