Hello friends, I hope all are fine. Today, we are going to share the 3rd chapter of Section-III in our Raspberry Pi Programming Course. In our previous lecture, we interfaced the Soil Moisture Sensor with Raspberry Pi 4 . Today, we are going to Interface the Infrared(IR) sensor with RPi4. IR Sensor is typically employed for the presence/motion detection of objects in the immediate area. With their low power consumption, straightforward design, and user-friendly features, IR sensors are a popular choice for detection purposes. Infrared(IR) impulses are invisible to the naked eye and lie between the visible and microwave parts of the electromagnetic spectrum. So let's get started: Components Required To learn how an IR sensor detects the existence of an object, we'll set up a basic circuit t ...
