1. Please define the term "ultrasonic sensor."
An ultrasonic sensor is a sensor that uses ultrasonic waves to measure distance, speed, and other physical quantities. The device makes measurements by emitting ultrasonic waves and receiving the waves reflected back from them.
2. What precautions should be taken when using ultrasonic sensors in outdoor environments?
When used outdoors, it is important to consider the ambient temperature, humidity, and wind speed in order to ensure optimal sensor performance. The selection of waterproof and dustproof designs for ultrasonic sensors can enhance their reliability in harsh environments.
3. Can ultrasonic sensors detect transparent or smooth surfaces?
Ultrasonic sensors are capable of detecting transparent or smooth surfaces, although the intensity of the reflected wave may be relatively weak. In these instances, it is crucial to select a more sensitive sensor.
