Living objects with a body temperature above 0°C emit heat as infrared radiation, also known as thermal radiation, which is invisible to the human eye. PIR sensors, designed for this purpose, can ...

The PIR (Passive Infrared) motion sensor is used to detect motion within a certain range. This project utilizes the PIR motion sensor to detect movement and trigger an LED to turn on using a Raspberry ...

This task involves using two sensors—a PIR sensor and a light sensor—to control an LED based on specific conditions. The system performs the following actions: • Movement without Light: Turns on the ...

While there are loads of impressive and complex projects here on Hackaday, sometimes it’s the simple ones that really speak to us. In this case we were presented with [Isabell Park]’s easy-to-follow ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

The complete circuit diagram for Arduino Based Decorative Christmas Tree is given above. It is pretty simple as we only need to connect a PIR sensor, JQ6500 voice module, and Neo-Pixel LED Strip. The ...

Abstract: Smart home is expected to offer various intelligent services by recognizing residents along with their life style and feelings. One of the key issues for realizing the smart home is how to ...

The main principle of the circuit is to provide security using PIR sensor. This can be used in the museums to protect the valuable things and also in defense applications to detect the humans in war ...
