U-Sensors (US)
The U-sensor (US) is a portable and disposable temperature and relative
humidity (RH) sensor.
The US is designed to be placed inside or near the monitored goods and
transmits measurements of the temperature and humidity at that location.
See Figure 2 for US unit, for detailed specification see Appendix
A.3: below
The US sensor should be placed in each pallet to monitor product through the
overall supply chain.
The US periodically measures temperature and relative humidity. When
connection is available to a U-Sensor Gateway, either directly or indirectly
through another sensor, the measurements are uploaded to the
communication server. When such connection is not available, measurements
are stored in a non volatile memory and will be uploaded once wireless
connection is re-established. See
3.3.7 for setup and installation.
