2.1.1.1
Activation of the US
The US unit is powered up by pressing the power button for 3
seconds.
2.1.2
U-Sensor LED Indications
The US contains one red LED indicator. The LED indicator is normally off in
regular operation. To make it active, and see the US state, the pushbutton
has to be pressed. There are two distinct patterns to indicate the status of
the US, as listed in Table 2.

LED Indicator
Description
1 sec single blink
Activation visual feedback. Pressing the pushbutton for three
seconds, while the US is not active, will cause the U-sensor to
go active and to make a single blink of one second
Flashing red
Network connectivity indication. Pressing the pushbutton for at
least one second, will cause the LED indicator to show the
connectivity sate of the US. A one second repetitive blink
means the US is not part of a sensor network and
measurements are logged in the sensor's memory
Constant red
Network connectivity indication. Pressing the pushbutton for at
least one second, will cause the LED indicator to show the
connectivity sate of the US. A constant on LED light means the
US is part of a sensor network and measurements are delivered
to the U-sensor gateway
2.2
M-Sensor (Air)
M-Sensors are targeted for outdoor applications such as metering, agriculture
and for integration with external sensors. The basic unit includes internal
temperature and RH sensors and has an option for an additional module with
extended RH capabilities. See Appendix
A.4: for detailed specification.
Pressing the pushbutton of an active U-sensor, the red light indicator should
light up in 1 sec (either continuously or blinking). If it does not light up, the
U-sensor has not been activated
