In this article, we are going to see how to work with the PIR sensor using Arduino. It has become very easy to detect human and animal movements using PIR sensor. These projects further can be modified to create a security system. Materials required PIR sensor module Arduino UNO LED Buzze...
How to use HC-SR501 PIR Motion Sensor with Arduino 15 Comments In this tutorial, you will learn how the HC-SR501 PIR motion sensor works and how you can use it with Arduino. You can find Passive Infrared (PIR) sensors all around you, they are not only used for security purposes, ...
Here’s the Arduino Code for this example. It’s quite simple. We just need to define the PIR Sensor pin as input and the relay pin as output. Using the digitalRead() function we will read the output of the sensor and if its high or if an object is detected it will activate the r...
In this tutorial we will check how to interact with a PIR motion sensor using an interrupt based approach, using theArduinocore running on the ESP32. In the previous tutorial, we covered the basics on how to interact with the PIR sensor. Nonetheless, we followed a polling approach, which ...
PIR Sensor for your Arduino APIRor Passive Infrared module is really fun to play with. This is what they look like: They are basically a motion detector and are called ‘passive’ in the sense that these devices do not generate any energy for detection purposes. They work entirely by ...
