用AD603提高超声波测距范围。超声波测距是一种非接触的测量方式，它是根据超声波从发射传感器到反射物体，再从反射物体到接收传感器的延迟时间.，利用距离/01. 2 ’，得到距离值，1 为声波在空气介质中的传播速度。由于反射超声波接收时的信号幅度与反射物体离接收传感器的距离远近有关，一般相差几十分贝-Ultrasonic Distance Measurement with the scope of AD603 improve. Ultrasonic Distance Measurement is a non-contact measurement, which is the ultrasonic sensor to the reflection from the launch of objects, objects from the reflector to the receiving sensor delay time., The use of distance/01.2, the distance values, one for the sound waves in air medium velocity. Receive as a result of reflection at the time of ultrasonic signal amplitude and the reflection from the object to receive the sensor distance, generally a difference of tens of decibels
