Today’s episode is about the magnetic Reed switch. In this tutorial, you will learn
1. What is a magnetic Reed switch
2. Uses of the magnetic reed switch
3. Types of the magnetic reed switch
4. How to make a door security system using gsm sim900A module and a buzzer.
Let’s get started.
A Reed switch is an electromagnetic switch which is used to control the flow of electricity in a circuit. It is an electrical switch and can be operated by applying a magnetic field. It was invented in Bell Telephone Laboratories in 1936. In a typical reed switch, the two contacts are made from a ferromagnetic material. Reed switches are most commonly used in
• Security systems, like for example sensing whether the doors and windows are open or closed. Which we will be practically implementing today.
• It is used in laptops when you lower your laptop screen, the laptop enters into the sleep mode, this is just because of the reed switch and magnet in action.
• It is used for safety in some devices such as food processors, The device won’t turn On unless a lid is shut or another safety precaution has been taken.
• It is used in automotive, some of the most common uses include, sensing the door positions, speed, braking, fuel levels, etc.
• Used in refrigerators, When you open the door the light turns on and when you close the door the light turns off.
The components that we will be needing for this project are
1. 7805 voltage regulator
2. Magnetic reed switch “normally open type”
3. 10K Resistor
4. 330-ohm resistor
5. 2n2222 NPN transistor
6. 5v Buzzer
7. Permanent magnet
8. 10uf capacitor
9. Led
10. Gsm sim900A module
11. Power supply for gsm module and finally
