A：
The installation of ultrasonic sensors must comply with the following requirements to ensure their measurement accuracy and stability:
Reasonable installation position
The sensor should be aligned vertically with the target surface to avoid large angle deviations to ensure that the sound waves are correctly reflected and returned.
Avoid interference
There should be no obstructions in front of the sensor to avoid false triggering or reflection interference from other objects.
Maintain a clean space
Avoid installing the sensor in dust, steam, strong wind or high humidity environments, and use a protective cover if necessary.
Avoid resonance interference
Do not fix the sensor in a vibrating position to prevent affecting the propagation of sound waves.
Fully consider blind spots
Ultrasonic sensors have a certain minimum detection distance (blind spot). When installing, ensure that the target object is beyond this range.
Correct wiring and power supply
Wiring according to the instructions to ensure that parameters such as voltage and current meet the sensor requirements.
Avoid mutual interference with multiple ultrasonic devices
If multiple sensors are used side by side, they should be installed staggered or set to different working cycles.
