3.4.4.1
Break-In Threshold
This parameter is the
𝑔
-threshold used for break-in detection. As soon as the
𝑔
-threshold is
tripped, a timer with a timeout is started. The timeout period is defined via Impact Debounce
Time (see Section 3.4.4.4). Within the timeout period, if the
𝑔
-threshold is tripped at least 4
times, a break-in alarm is raised.
3.4.4.2
Impact Threshold
This parameter is the
𝑔
-threshold for an impact event. Impact events are reported immediately
once they are triggered. Impact Threshold is greater than 0 (zero). A value of 0 (zero) is ignored.
3.4.4.3
Value to Transmit
When an impact event is registered or when the accelerometer is periodically polled, the data
to transmit can be configured by the end user. Available types are:
•
Alarm: A single data byte to indicate that the Sensor was tripped.
•
Magnitude: A single RMS value for the X/Y/Z accelerometer reading.
•
Full-Precision: milli-
𝑔
values for each X/Y/Z axis of the accelerometer.
3.4.4.4
Impact Debounce Time
The accelerometer is disabled for a configurable time frame after an event is registered. This is
done to prevent a single impact from transmitting multiple events. The minimum debounce
time is 1 (one) second.
3.4.4.5
Mode
The accelerator can be powered on/off to tune power usage (battery life) for end-user
application. Additionally, Impact and Break-In thresholds can be enabled/disabled. Disabling a
threshold prevents the Sensor from generating the applicable accelerometer event.
