This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Circuit Diagram. Here the Nokia 5110 LCD is used to display the Light level and distance.The Nokia 5110 LCD operates at 3.3V so it can’t be connected with Arduino Nano digital pins directly. So add ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

A distance sensor with Arduino microcontroller. This simple sensor can measure the distance from a surface. Based on the property of an LED to act as a photodiode, that is, a photodetector able to ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need … ...

The treat in question is detected by an SR-04 ultrasonic distance sensor connected to an Arduino Nano. ... The shoe’s view — safe walking space is delimited with color. Image via TU Graz.

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 ...
