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 ...

Previously, we have build many robots using arduino including an Obstacle Avoiding Robot using Arduino Uno and Ultrasonic Sensor, you can also check them out if you are interested. In this ...

This paper shows non-contact water level monitoring system implemented using LabVIEW and arduino. Water depth of the tank is measured by Ultrasonic sensor. Hence the water level present in the tank is ...

It’s an Arduino controlled “RADAR” like project that uses the familiar Parallax ultrasonic sensor.

Vehicle over-speed detection and accident-avoidance system is an Internet of Things (IoT) based system which collects data via sensors such as ultrasonic sensors and alerts the driver. The sensor is ...
