🛠️ Components Used 🔹 Arduino Uno – Microcontroller for processing sensor data. 🔹 HC-SR04 Ultrasonic Sensor – Measures distance using sound waves. 🔹 LEDs (5x) – Visual indicators for different ...

1. The **HC-SR04** emits ultrasonic waves and measures the time it takes for them to bounce back. 2. The **Arduino Nano** calculates the distance using the speed of sound. 3. If an object is detected ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...

The JSN-SR04T Waterproof Ultrasonic Sensor As well as the familiar ultrasonic ranging module HC-SR04, another one seen on online markets is the JSN-SR04 (and variants). The JSN-SR04 ultrasonic ranging ...

The ultrasonic sensors act as distance measuring device as they reflect back the waves from the object and distance is measured just like the animal bat traces its path. Published in: 2021 ...
