Alarm-System Alarm System created with Arduino equipped with sounds sensor and ultrasonic sensor to detect motion. Alarms system with a four digit security code. The alarm system uses an ultrasonic ...

What does the motion sensor do? Prototype I was designed using an ELEGOO Mega board, LCD, Ultrasonic Sensor, buzzer, and a 4x4 matrix keypad. Fig. 1.1 shows the internal wiring used for prototype I.

This project uses Arduino and Android to create a surveillance device which uses ultrasonic sensor to broadcast the information to a mobile application using bluetooth.

In this project we have used an Arduino and Ultrasonic Sensor to determine the distance of an obstacle from the sensor. Basic principal of ultrasonic distance measurement is based on ECHO.

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 ...

Abstract In this study, a simple Arduino-based experiment was designed to examine the acceleration of the object during free fall and to calculate the value of “g” (acceleration due to gravity).

The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the ...

The application of sensors in smart homes using Arduino to control equipment such as lights, fans, alarms, and so on. Sensors used in Arduino include LDR, Ultrasonic, DHT11, and MQ2. LDR is used to ...
