PIR sensors allow you to sense motion. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. Now, the big question is that how it will detect the human activities? Do not worry, this tutorial will guide you about the PIR sensor working principle. What is a PIR Sensor? A passive infrared sensor is an electronic sensor that measures infrared light radiating...
