Summary of Aprendiendo a usar un módulo PIR (sensor de movimiento)

00:00:00 - 00:05:00

In the video, we learn how to use a PIR sensor module to detect movement. The module is easy to program and can detect even small movements. In the next video, we will learn how to use the module to control a robot.

• 00:00:00 In this video, we'll learn how to use a passive infrared (PIR) sensor. This type of sensor detects movement by measuring radiation in the infrared spectrum. It's passive because it doesn't emit radiation itself, but rather receives it and detects its main component, the electronic sensor. The sensor we're using is called a HC-SR501, and it's commonly called a "shifter internet" because it's used to detect movement on the internet. Like most passive sensors, it has a temperature-dependent radiation emitted from the body. When anything passes over the sensor's range of 273 degrees Fahrenheit, it will cause a temperature change and infrared radiation to be detected by the sensor. This information is then processed by the Arduino.
• 00:05:00 In this video, we learn how to use a PIR (sensor of movement) module. It is easy to program and is something much more complex than we will see. We will see how it works and check its function by putting my hand in the middle of the module and detecting when I move. As you can see, the LED lights up when I move. We were able to keep the module completely still, and the LED would stay off, if we were able to do this. However, if I move, the LED will light up. The module is able to detect even small movements. We will learn next how to use the module without the need for a microcontroller. Finally, in the next video, we will learn how to use the module to control a robot.
