Ultrasonic Sensor Module There are many types of Arduino distance sensors, but in this project we have used the HC-SR04 to measure distance in range of 2cm-400cm with an accuracy of 3mm. The sensor ...

Mini-Water-level-detection-using-Arduino- THIS repository may help you to make a mini water tank level detection using ultrasonic sensor,arduino and Blynk Application. this code can be compiled in the ...

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 ...

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 ...

Hardware system consist of basically 3 components named as Arduino, servo-motor, and ultra-sonic sensor. Ultrasonic sensor is mounded upon a servo motor which helps it to move and provide it a turning ...

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.
