How to Use a PIR Sensor with Arduino (Lesson #26)

This video tutorial explains how to use passive infrared (PIR) sensors with Arduino for motion detection. It covers the working principle of PIR sensors, their components, and how to connect them to an Arduino. The tutorial also discusses adjusting sensor settings like sensitivity and delay, and provides a simple circuit and code to control an LED based on motion detection. The video emphasizes the importance of checking the sensor's datasheet for correct connections and settings.

What is the primary function of a passive infrared sensor?

Explain how passive infrared sensors detect motion.

What are the three pins typically found on a passive infrared sensor?

What should you check on the data sheet of a passive infrared sensor?

How can you restrict the field of view of a passive infrared sensor?

Describe the connection process of a passive infrared sensor to an Arduino.

What is the significance of the delay after motion is detected by the sensor?
