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
7. Installation
Kindly note the illustration is only for reference.
1.
The device can be installed in the middle or anywhere of the top of the container that is flat enough to ensure the ultrasonic
detection direction will be vertical to the detected object, so the accuracy can be maintained.
2.
When the use case is water tank, the diameter of the water tank is recommended to be larger than 60cm.
3.
Customers can refer to the below formula to see if the container is suitable:
tan7.5°=A / B
A
is the radius of the container (water tank),
B
is the height of the container (water tank);
