A relative air humidity sensor is connected to NetPing server room environmental monitoring units and power distribution units, that support a 1-wire interface. A sensor is plugged with the help of a RJ12 plug, in which all 6 contacts are used. Electrically, all 1-wire sensors are connected in parallel to each other, therefore it does not matter to which 1-wire socket on a body of a device a sensor is connected.
To increase a sensor cable length, use special 1-wire cable extenders. A 1-wire splitter is included into a cable extender kit. It allows to branch a sensor network anywhere. An overall cable length of a 1-wire network must not exceed 50 meters. If necessary, it is possible to extend sensor flat cables without assistance, using a 6-wire cable, at least AWG24. There is a need to use special equipment for crimping RJ12 sockets. Use a 1-wire splitter to connect a sensor.
1-wire humidity sensors have unique internal numbers, which allow a device to identify each sensor. When connecting a new 1-wire sensor to a server room environmental monitoring units and power distribution units, there is a need to complete a procedure of a device reading an internal number. See more detailed information about a sensor plugin in a document "Firmware Description" for the device, to which you connect a sensor.
A digital humidity sensor is designed on a basis of a single-chip sensor HIH-4000. A temperature sensor, which is built-in a humidity sensor is made on basis of a chip DS2438.
