6.2. Uplink Messages
The uplink message (sensor to web application) specific to the sensor is defined in following
table. The common uplink messages are not included in this section (see common messages
document).
Table 5 Uplink Message 0x0F: High-Precision Tilt Event
Byte Description
0x00 Tilt event
0x01 Tilt angle from vertical axis – whole degrees
0x02 Tilt angle from vertical axis – fractional degrees
0x03 Temperature in degrees C
The high-precision tilt sensor has precision to 0.1 degrees. Byte 1 of the uplink message is the
whole integer component and byte 2 is in tenths of a degree. For example, a measurement of
48.7 degrees would be represented as 0x30 and 0x07 respectively.
The tilt events are defined in the following table.
Table 6 Uplink Tilt Event Definitions
Event Description
0x00 Periodic report
0x01 Sensor transitioned toward the 0-degree vertical orientation
0x02 Sensor transitioned away from the 0-degree vertical orientation
0x03 Report on change toward the 0-degree vertical orientation
0x04 Report on change away from the 0-degree vertical orientation
The first two event messages are sent when the tilt angle exceeds the threshold toward or
away from the 0-degree vertical orientation. Note that the angle is relative to a 0-degree
vertical orientation, so small angles will be reported when the sensor is oriented vertically.
