Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...

This is a program for detecting and alerting when motion is detected ... Connect the PIR sensor to digital pin 2. int buzzerPin = 3; // Connect the Buzzer to digital pin 3. int ledPin = 13; // ...

The objective of this experiment is to use a PIR motion sensor ... group of students could take this build and use it for other commonly used house appliances, such as a toaster, television, shower, ...

However, when motion ... project will look like this. The output of the PIR sensor can also be seen on serial monitor. This blog provides a step-by-step guide on creating a practical and ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go. If that sounds ...

This voltage can be read by an Arduino digital input and then the Arduino can act upon it. The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes ...

Anyone searching for an Arduino ... by the motion sensor, it takes a picture. Images are posted to io.adafruit.com using the REST API.” “There’s also the fact that this project uses a ...
