An opposite-type ultrasonic ranging system based on the low-cost HC-SR04 integrated module is designed. The different time sequences and sampling methods are measured, which may affect system performance, and different MCU control schemes are compared on the measuring results. Experimental results show that ranging errors of the calibrated ranging system are within 1.0 centimeter, which can meet the needs of a large range of applications, such as point to point positioning, distance measuring, and some specific security monitoring environments.
