Abstract: Ultrasonic ranging is mainly used in reversing radar, construction sites and some industrial sites, such as liquid level, well depth, pipe length and other occasions. At present, an ASIC is generally used in China to design an ultrasonic range finder, but the cost of the ASIC is high, and it is not displayed, and the operation is inconvenient. This article uses the Atmega16 microcontroller as the core to introduce how to make a low-cost, high-precision, miniaturized digital display ultrasonic range finder. First, the principle of ultrasonic measurement Ultrasonic is a relatively high frequency, strong directivity. The principle of ultrasonic ranging is to use the propagation speed of ultrasonic waves in the air to be known, to measure the time when the acoustic waves are reflected by the obstacles after the launch, and calculate the actual distance from the launching point to the obstacle according to the time difference between the transmitting and receiving.
