1.The influence of ultrasonic propagation speed on rangingStable and accurate ultrasonic propagation velocity is a necessary condition to ensure measurement accuracy. The propagation speed of a wave depends on the characteristics of the propagation medium. The temperature, pressure, and density of t

Accuracy of ultrasonic ranging sensor module: ±(1cm+0.5%×distance), which is relatively low. The principle of ultrasonic ranging is to use the known propagation speed of ultrasonic waves in the air to measure the time when the sound wave encounters obstacles and reflect back after transmission, and
