6. Application
In the case of detecting the material level of the barn, the device is installed on the top of the barn, and the device is powered on
after fixing. The device collects the distance between the material level and the sensor and the percentage of the material level in
the barn at regular intervals.
H
: The height of the barn (this value can be set with the payload command; the “fillmaxdistance” in payload means H)
D
: The distance between the device and the material (this value is “distance” in uplinks)
L
: The material level (this value can be calculated by the “distance” in uplink and “fillmaxdistance” in payload)
Calculation: L = fillmaxdistacnce – distance
d
: The DeadZoneDeistance set by the device (the distance that cannot be detected by the actual device)
FillLevel
: The percentage of the material level in the barn.
The value of the total height of the barn can be set through commands according to the specific scene.

FillLevel = ((H - D) / H) * 100%
FillLevel = ((H - D) / H-d) * 100%
Note:
(1) The detecting range of the device is 250mm~8000mm
(2) When the device is used as level / material level detection, the detected distance (Distance) and the percentage of material level
(FillLevel) are reported. Otherwise, the parking status (Status) is not reported (in this case, Status is 0 by default).
(3) When the device is used as parking space detection, it will report the detected distance (Distance) and the parking status (Status)
(with car, report “on”; without car, report “off” ), but FillLevel is not reported. (At this time, FillLevel defaults 0.)
(4) When Distance
≤
OnDistanceThreshold, the status is reported as on, so OnDistanceThreshold is recommended to be set to be less
than the distance under the condition of no vehicle
The calculate method of material level percentage of
DeadZoneDistance can be set
