Raspberry Pi For Beginners - 2022 Complete Course - Read the PIR's Data with Python

The video tutorial explains how to set up and use a PIR sensor with a Raspberry Pi. It covers the initial calibration period required for the sensor, the connection process to the Raspberry Pi using GPIO pins, and the use of pull-up and pull-down resistors to ensure stable data readings. The tutorial also demonstrates how to read data from the sensor using Python, highlighting the importance of using internal resistors to avoid unreliable results. The PIR sensor detects movement by reading high or low values, similar to a push button.
