If your unit is magnetically mounted, please do not screw through mounting tabs. This
could cause damage to the mounting tabs because the magnets prevent the tabs from
being flush with the mounting surface.
STU RF WIRELESS SENSORS
Up to 10 RF wireless sensors are available for each STU. Each RF wireless sensor can measure:
1.
Tilt in two different axis
2.
Door/hatch open and close via magnetic reed switch
3.
Temperature
4.
Its own battery voltage
The RF sender is an event based sensor. It will send data to the STU upon a triggered event (such
as open door/hatch). The sender does not send any periodic transmissions to the STU.
The STU can be set to send out a report on the receipt of each RF message (over the air
configurable). The STU can also be set to take a picture on the receipt of a digital change of
state/RF message being received.
Tilt Sensor:
Measures an analog value of the tilt reading and also a digital that the tilt changed by more
than X (X is programmed here at Lat-Lon when we make the unit). The tilt also creates a
digital value of 1 when it’s at the high-end of its range and 0 when it’s at the low end of its
analog range. This is useful for loaded/empty or hatch open/closed where orientations
change from one zone to another.
Digital Reed Switch:
The digital reed switch reports a change of state as well whether the door/hatch was opened
or closed since the last timed report. Note that 1 end of the sensor says “Reed Switch”.
