The ultrasonic sensor uses sonar to determine the distance to an object. Here’s what happens: The ultrasound transmitter (trig pin) emits a high-frequency sound (40 kHz). The sound travels through the ...

Overview This Task uses an Arduino, an ultrasonic sensor, an IR sensor, an LCD display, and LEDs to measure distance, detect motion, and respond to a button press. The system displays distance ...

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 ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...
