此外,如果您的设备上的HC-SR04传感器安装不足,您可能会检测到地板反射的声音。 d)在对传感器进行试验时,我们发现一些具有柔软,不规则表面的物体(如填充动物)吸收而不是反射声音,因此HC-SR04传感器很难检测到。 温度对距离测量的影响 虽然HC-SR04对于我们的大多数项目来说都是相当准确的,例如入侵者检测或接近警报; ...
HC-SR04 Ultrasonic Sensor - Working As shown above theHC-SR04 Ultrasonic (US) sensoris a 4 pin module, whose pin names are Vcc, Trigger, Echo and Ground respectively. This sensor is a very popular sensor used in many applications where measuring distance or sensing objects are required. The ...
In this case, we need this set to it HIGH, as the HC-SR04 sensors sets the Echo pin to High after sending the 8 cycle ultrasonic burst from the transmitter. This actually starts the timing and once we receive the reflected sound wave the Echo pin will go to Low which stops the timing...
