Description: 1. A Reed Switch is an electromechanical switch that utilizes a magnetic field to activate or deactivate the circuit. It consists of two metal contacts enclosed in a glass tube filled with an inert gas. 2. Features: Simple design, low power consumption, reliable operation, long lifespan (up to 5 million cycles), and no moving parts except for the contacts that are sealed from the environment. 3. Usage: Reed Switches are commonly found in applications such as door sensors, level switches, proximity detectors, and fuel tank level indicators due to their ability to operate with minimal external force. 4. Magnetic Actuation: When a magnet is brought near the Reed Switch, it alters the magnetic field within the glass tube and causes the contacts to snap into the closed position, completing the circuit. 5. Non-Magnetic Actuation: Reed Switches can also be actuated by non-magnetic means, such as thermal expansion or vibration, depending on the design of the switch. 6. Benefits in IoT: I
