• The principle of ultrasonic ranging

  The sound wave frequency that human ears can hear is 20HZ～20KHz. When the frequency is higher than 20KHz, the human ear cannot hear it. Therefore, we call the sound wave with a frequency higher than 20KHz "ultrasonic wave".Ultrasound has a strong directivity and travels a long distance in the air.

• Why buzzer has noise

  When the sound of the buzzer is not a crisp and simple hum, we will call it a murmur or a broken sound. The cause of the buzzer noise can be divided into two possibilities.First, there are problems with the way of using:The voltage to the buzzer is too high: the diaphragm hits other parts inside the
