In this video, we will learn about the **Reed Switch Magnetic Sensor** and how it is used as a **Door Opening Sensor**. Reed switches are commonly used in **security systems, alarm systems, and automation projects** to detect whether a door or window is open or closed.
In this tutorial, you will learn:
• What is a **Reed Switch**
• How a **Magnet activates the Reed Switch**
• Reed Switch **Working Principle**
• How to **Test a Reed Switch using a Multimeter**
• How Reed Switch is used as a **Door Open / Close Sensor**
This sensor is widely used in **home security systems, IoT projects, Arduino projects, and smart automation systems**.
