• System may not sense obstacles like wire mesh, handrail, small
objects which are below the bumper level
• System may not sense obstacles with cotton or spongy surface,
which will absorb ultrasonic waves emitted by RPAS
• System performance is dependent on the reflection angle of the
obstacle
• System may give false alert without obstacles while reversing the
vehicle on grasslands, gravels and bumpy roads considering it to
be an obstacle
• System may alert you by sensing the ground when the bumper is
not fitted in its intended position or when the vehicle is
overloaded
• System may give false signal while the vehicle moves from plain
ground to a slope terrain and vice versa
• System may give false signal by sensing the ground when the
bumper is tilted more from the normal position or when the
vehicle is heavily overloaded
• System may give false signal an alarm during heavy rain, snow
and heavy wind conditions
• The shape of the obstacle may prevent a sensor from detecting
it. Some obstacles for example as follows:
– Sharply-angled objects
– Tall or curved curb
– Low obstacles (with height of 40 cm above ground level)
– Tall obstacles with upper sections projecting outwards in the
direction of the vehicle
• Depending upon the shape of the obstacle and other
environmental factors, the detection distance may shorten or
detection may be impossible
• Obstacles may not be detected if they are too close to the
sensor
• Thin posts or objects lower than the sensor may not be detected
when approached, even if they have been detected once
• Because of other ultrasonic sources, sensor may give false
alarm for e. g., sweeping machines, high pressure steam
cleaners and neon lights
• Due to vehicle horns, motorcycle engines, air brakes of large
vehicles, or other loud noises producing ultrasonic waves, the
vicinity of the vehicle is noisy. It may cause sensor to give false
alarm
