Unidirectional Tilt Sensor Switch | Mercury-Free On/Off 5mm

This is a simple tilt sensor. It acts as an on/off switch. It only activates when tilted in one direction. These sensors are mercury-free. They come in 3mm or 5mm sizes. You can use them in various electronics projects. Features and Benefits - One-way activation - The circuit closes only when tilted past a certain angle. This offers precise control. - Mercury-free ball design - A small metal ball makes or breaks the connection. This makes the switch safer to handle. It's also better for the environment. - Simple two-terminal contact - It works like a basic switch. This makes it easy to read as a digital input on microcontrollers like an Arduino. - Small 3mm and 5mm bodies - The small size lets this miniature tilt switch fit easily onto crowded circuit boards. It also fits inside small device housings. Applications - Robotics - Use it to detect if a robot has tipped over. Or sense the angle of an arm or platform. - Security Systems - Use it as an on/off switch for security systems. It can trigger an alarm if a window, door, or valuable object moves. - Interactive Projects - Add motion activation to toys or art installations. For example, light up an object when it's picked up or tilted. Mechanical Ball / Rolling-Element Switches (Simple On/Off) This Tilt Sensor operates as an On/Off switch, making it a type of mechanical ball or rolling-element switch. Inside, a conductive element, often a small ball, moves with the tilt of the sensor. When the sensor is tilted beyond a certain angle, this element completes an electrical circuit, switching it 'on'. When tilted back, the circuit is broken, switching it 'off'. This simple mechanism is ideal for basic tilt detection in DIY alarms, where a clear on/off signal is required when the device is moved or disturbed. MEMS Accelerometers (Precise Angle Measurement) Unlike the simple On/Off operation of this product, MEMS (Micro-Electro-Mechanical Systems) accelerometers offer a more sophisticated method for precise angle measurement. They work by detecting acceleration along one or more axes. Gravity itself is a form of acceleration (1g), and as the sensor tilts, the accelerometer measures the change in the component of gravity acting on each axis. This allows for continuous and highly accurate determination of tilt angle, rather than just an on/off state. MEMS accelerometers are often found in applications requiring detailed orientation data. Optical Tilt Sensors Optical tilt sensors use light to detect changes in orientation. They typically involve an emitter, such as an LED, and a receiver, like a photodiode, alongside a reflective or obstructive element. As the sensor tilts, the path of the light between the emitter and receiver is altered, either by reflecting off a surface or being blocked by an object. This change in light intensity or path is then converted into an electrical signal, indicating the degree of tilt. These sensors can offer contact-free operation and are used in various precise applications. Quick Comparison The Tilt Sensor offered here is a 5mm On/Off switch, designed for straightforward tilt detection. - Mechanical Ball Switches: Simple On/Off, ideal for basic alarms. This product falls into this category. - MEMS Accelerometers: Provide precise angle measurement, offering continuous data on tilt. - Optical Tilt Sensors: Use light to detect tilt, often offering non-contact operation. This product provides a clear unidirectional On/Off signal, suitable for applications needing a sensitive switch response to tilt. The Gravity Sensor A gravity sensor, often synonymous with a tilt sensor or accelerometer, works by detecting the force of gravity (1g) acting upon it. When the sensor is stationary, the gravity sensor measures the component of this force along its internal axes. As the sensor tilts, the distribution of this force changes, allowing the sensor to determine its orientation relative to the Earth's gravitational pull. For an On/Off switch like this Tilt Sensor, it means that when the device is moved or shaken, the change in the gravity vector causes the internal mechanism to switch from an 'off' to an 'on' state, triggering the DIY alarm.
