The code for controling ultrasonic sensor with Metro M4 Express (Adafruit) with ROSserial protocol uploaded in file name ultrasonic sensor. Circuit diagram for connecting 3 ultrasonic sensors with ...

This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

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 ...

Adding cameras and vision algorithms to your projects and robots might sound cool but sometimes it becomes expensive in terms of both capital and time. When the task at hand is much simpler like ...

VCC This pin is used to supply power to the sensor. It typically requires 5V DC power supply. Trig (Trigger) This pin is used to send a trigger signal to the sensor. When a HIGH signal (usually 5V) is ...

The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

Abstract: A compact fiber-optic ultrasonic sensor based on the anti-resonant reflecting optical waveguide (ARROW) in hollow core fiber is proposed and demonstrated experimentally. The proposed sensor ...
