SunFounder ESP32 Starter Kit
The ultrasonic sensor in the project emits high-frequency sound waves and measures the time it takes for the waves
to bounce back after hitting an object. By analyzing this data, the distance between the sensor and the object can
be calculated. To provide a warning when the object is too close, a buzzer is used to produce an audible signal.
Additionally, the measured distance is displayed on an LCD screen for easy visualization.
