Ultrasonic Sensor Module: Ultrasonic sensor HC-SR04 is used here to detect the presences of any person at the door. The sensor module consists of ultrasonic transmitter, receiver and the control ...

This time measurement helps calculate the distance between the sensor and the object. Ultrasonic sensors are widely used in applications such as distance measurement, object detection, liquid level ...

To create a 2-Dimensional Radar which maps the surroundings using SONAR (Ultrasonic Sensors) and Arduino-UNO microcontroller, which displays the distance of obstacles from the SONAR. This project ...

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 ...

Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

These ultrasonic sensors will send an Ultrasonic wave using the ultrasonic transmitter of the sensor. These ultrasonic waves travel through air and on colliding with an obstacle, get reflected back.

Abstract: 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 ...
