Q. Please explain
what mutual interference is, and how I can prevent this from occurring.
Mutual interference occurs when ultrasonic sensors
are mounted in close proximity to each other and the target is in
a position to reflect echoes back to a sensor near the transmitting
sensor. To reduce the chance of this occurring, mount adjacent sensors
as far apart as possible, and test the sensors with the target object
placed in the sensing range of one of the sensors. If any of the other
sensors detect the echo from the originating sensor and target object,
then re-position the sensors, either through spacing them further
apart, or angling the sensors away from each other.
