General Description:

Mini Reed switches are mechanical devices that are triggered by a magnet, causing the magnetic field to pull the metallic switch contacts together. These switches are valued for their compact size, low power consumption, and reliability.

Working Principle:

A mini reed switch operates using two ferromagnetic reeds sealed in a small glass tube. In its resting state, the reeds are separated, keeping the switch open. When an external magnetic field is applied, the reeds become magnetized and attract each other, closing the switch and allowing current to flow. Removing the magnetic field causes the reeds to demagnetize and separate, opening the switch and stopping the current flow. This mechanism ensures precise and reliable switching without physical contact with the actuating magnet.

Specifications:

1. Operates within a range of 3.3V to 5V.

2. Output is digital, meaning the switch provides a clear ON/OFF signal.

Applications:

1. Automotive industries utilize mini reed switches for monitoring door positions and seatbelt status.

2. Used in mechanical systems as proximity sensors.

3. Used for position detection in production processes, as well as the measurement of tank levels in the chemical, pharmaceutical, and food industries.

4. Used in medical devices where they detect movable parts or assist in patient positioning.

General Description:

A Tilt Sensor, also known as a Tilt Switch, detects the orientation of an object, though it doesn't measure the angle of tilt as accelerometers do. Instead, it indicates whether the sensor is tilted or not.

A Mercury switch-based tilt sensor module outputs high when tilted, requiring a 5V DC input. It typically has three terminals: input, ground, and output. Inside, there's a glass tube with two electrodes and a liquid mercury ball. When the sensor is tilted in a particular direction, the mercury ball moves, opening or closing the circuit.

Working Principle:

Tilt sensors are made up of a plastic or glass tube, with two pieces of wire and a metal ball inside:

When the tube is tilted forward, the ball rolls forward and only contacts one wire.

When the tube is tilted backward, the ball rolls back and contacts both wires.

This allows current to flow between the two wires. We can detect this high or low signal with the Arduino to determine if the sensor is tilted or not.

Specifications:

1. Tilt sensor consists of 3 pins: GND, VCC, DO (Output Signal).

2. Operating Voltage: 3.3 V to 5 V.

3. Maximum output current: 15mA.

4. Output Type: Digital.

5. Tilt Angle Threshold: Typically, around 45° (can vary depending on model).

Applications:

1. Interactive Games and Toys.

2. Security and Alarm Systems.

3. Automation and Robotics.

4. Art installations and Displays.

General Description:

The Linear magnetic Hall sensor reacts in the presence of a magnetic field. It has a potentiometer to adjust the sensitivity of the sensor and it provides both analog and digital outputs. The digital output acts as a switch that will turn on/off when a magnet is near. On the other hand, the analog output can measure the polarity and relative strength of the magnetic field.

Working Principle:

Hall Effect sensor module is used to detect the proximity of a magnet. It is much smaller in size, when the magnetic field rises above a threshold level, the open collector output transistor switches on, which pulls the logic-compatible output low and illuminates the onboard LED indicator.

General Description:

It is a fire flame detection sensor relay Module. The flame sensor can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighter distance of 80cm, the larger the flame, the greater the distance test.

General Description:

A slide switch is a type of bistable switch with two stable positions that control the flow of current in a circuit. It can be toggled between open and closed positions by sliding its actuator. These switches will stay in one position until changed into another position manually. A slide switch can also be used to connect two further circuits to an existing one and to connect them optionally.

Working Principle:

The working principle of a slide switch revolves around its internal mechanism of movable metal contacts within a housing. When the actuator or slider is moved, it physically shifts these contacts to either make or break electrical connections. In the closed position, the contacts come into contact, allowing current to flow through the switch and complete the circuit. Conversely, in the open position, the contacts are separated, interrupting the current flow. It's this straightforward functionality that makes slide switches a popular choice for many devices.

Specifications:

1. It has a current rating of 25mA.

2. Can handle up to 24VDC of voltage.

3. The actuator type is a Slide (Standard) and actuator level is raised.

4. Contacts are made from copper alloy with a gold finish.

5. It is designed for operation in temperatures ranging from -40°C to 85°C.

Pin Diagrams:

Applications:

1. Slide switches are often used to turn flashlights on and off.

2. Found in dashboards and control panels for operating lights, wipers, and other vehicle functions.

3. They're also used in more industrial applications to control electrical circuits in machinery or equipment.

4. Used in devices like small radios, portable music players and other consumer electronics.
