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.

In this project we are going to discuss how to use Ultrasonic sensor (Distance /Range Finder) with arduino micro-controller .We will be getting the object distance or range of an object on the Serial ...

Ultrasonic Module with Arduino Connection Diagram The Following connections are made between Arduino UNO and the Sensor: Arduino Code As discussed in the working section, we need to send 10uS pulses ...

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 ...

How the Arduino ultrasonic sensor actually works To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...
