Vibration Sensor | Real-Time Shock Alerts | Tuya WiFi & Zigbee

This wireless vibration sensor alerts you to shock, tilt, or impact on any surface. You can choose a WiFi model that connects to your router. Or, pick a Zigbee version that pairs with a smart hub. Both send real-time alerts to your phone using the Tuya Smart Life app. Features and Benefits - WiFi or Zigbee Options - Pick the WiFi version for simple setup. Or, choose the Zigbee model for use with Home Assistant and other hub-based systems. - Adjustable Sensitivity - Set the trigger level from low to high. This avoids false alarms from minor bumps or vibrations. - Real-Time Notifications - The sensor instantly sends a push notification to your phone when it detects activity. - Compact and Wireless - The small, battery-powered design and adhesive backing let you place it discreetly. Put it on doors, windows, or valuables. Applications - Door and Window Security - Get an alert if a window is broken or a door is forced open. - Protecting Valuables - Attach it to a safe, drawer, or jewelry box. This monitors for unauthorized access. - Appliance Monitoring - Stick it on a washing machine or dryer. You get a notification when the cycle is finished. The Main Types of Vibration Sensors A vibration sensor, sometimes referred to as a vibration switch or a module, detects and measures mechanical oscillations. These devices translate physical movement into an electrical signal, which can then be analysed. This particular product is a Vibration Sensor capable of real-time shock alerts. It uses either WiFi or Zigbee for wireless communication, making it compatible with the Tuya Smart Life app. Understanding how a vibration sensor works often depends on its underlying technology, as different types are suited for various applications, from simple presence detection to complex machinery monitoring. Piezoelectric Accelerometers (The Industrial Gold Standard) Piezoelectric accelerometers are a common type of vibration sensor, widely used in industrial settings due to their robustness and high-frequency response. These sensors work on the principle of the piezoelectric effect: when a mechanical stress is applied to certain materials, they generate an electrical charge. In an accelerometer, an inertial mass is attached to a piezoelectric crystal. When the sensor vibrates, the mass exerts a force on the crystal, producing a voltage proportional to the acceleration. This allows the sensor to detect and quantify the magnitude of vibrations. MEMS Accelerometers (The Silicon Micro-Sensors) MEMS (Micro-Electro-Mechanical Systems) accelerometers are miniature vibration sensors, known for their compact size and low power consumption. These silicon-based devices incorporate microscopic mechanical elements and electrical circuitry on a single chip. They typically work by detecting changes in capacitance as a proof mass moves in response to acceleration. This movement alters the gap between fixed and moving plates, changing the capacitance, which is then converted into an electrical signal. This Vibration Sensor is a compact, black unit, powered by a battery, making it suitable for discreet monitoring. Eddy Current / Inductive Proximity Probes Eddy current or inductive proximity probes are a type of non-contact vibration sensor primarily used for measuring the displacement of conductive targets. These sensors generate an alternating magnetic field from a coil. When a conductive material enters this field, eddy currents are induced in the target, which in turn alter the impedance of the sensor's coil. The change in impedance is proportional to the distance between the sensor and the target. This allows for precise measurement of small movements, such as shaft vibration in rotating machinery. Strain Gauges & Piezoresistive Sensors Strain gauges and piezoresistive sensors detect vibration by measuring changes in electrical resistance due to mechanical deformation. A strain gauge consists of a thin metallic foil or semiconductor material that is bonded to a surface. When the surface vibrates, the material deforms, causing its electrical resistance to change. Piezoresistive sensors work on a similar principle but often use semiconductor materials that exhibit a larger change in resistance for a given strain. This allows the sensor to convert mechanical strain directly into an electrical signal, indicating the presence and intensity of vibration.
