Solar Motion Sensor Alarm | Wireless Photoelectric Security System

This solar motion sensor alarm protects your property without needing any wires. It senses movement up to 12 meters away. Then it sounds a loud 110dB siren and flashes a bright strobe light. A built-in tilt sensor also sets off the alarm if someone tries to move it. Features and Benefits - Solar Powered and Wireless - The solar panel keeps the battery charged. It works day and night. Just mount it and turn it on. - Motion and Tamper Detection - An infrared sensor spots people and large animals. An internal tilt sensor stops tampering. - Loud Siren and Strobe Light - The 110-decibel alarm is very loud. It warns you right away and scares off intruders with a bright flashing light. - IP65 Weatherproof Construction - The alarm is made to handle rain, snow, and sun. It provides dependable security outdoors all year. Applications - Home Perimeter Security - Put it on a shed, garage, or fence post. This secures your yard, driveway, or other vulnerable spots. - Farm and Acreage Protection - Use this solar powered motion detector siren to guard equipment, animal pens, or remote gates from theft. - Job Site Monitoring - Keep an eye on tools and materials at a construction site or in a storage yard after hours. Mechanical Ball / Rolling-Element Switches (Simple On/Off) These are fundamental tilt switches. They operate on a simple principle: a conductive ball or rolling element within a housing completes or breaks an electrical circuit when tilted past a certain angle. This makes them effective as simple on/off switches for detecting changes in orientation. For instance, if this Powered Tilt Sensor were to utilise such a switch, a significant tilt would trigger its 110dB siren and strobe light. These switches are typically robust and reliable for basic tilt detection, indicating a status change rather than a precise angle. MEMS Accelerometers (Precise Angle Measurement) MEMS (Micro-Electro-Mechanical Systems) accelerometers are sophisticated tilt sensors capable of measuring acceleration along one or more axes. This allows for precise angle measurement, unlike simple on/off tilt switches. They detect changes in orientation by sensing the force of gravity (1g) acting upon the sensor. If the Powered Tilt Sensor employed a MEMS accelerometer, it could offer more nuanced detection of movement within its 120° detection angle. This technology is often used for applications requiring accurate monitoring of slight shifts or inclinations. Optical Tilt Sensors Optical tilt sensors use light to detect changes in angle. This can involve a light source and a detector, where the path of light is interrupted or redirected by a moving element as the sensor tilts. Alternatively, some optical sensors use a reflective surface that changes position with tilt, altering the reflected light detected. While the specific sensor type for this product is an infrared motion sensor, optical tilt sensors offer non-contact detection and can be highly sensitive. They are often chosen for environments where mechanical wear is a concern, or where very precise and repeatable measurements are needed. Quick Comparison Understanding how a tilt sensor works is key to its application. Simple mechanical ball switches offer basic on/off detection, ideal for triggering an alarm like the 110dB siren on this product for a clear change in state. MEMS accelerometers provide precise angle measurements, suitable for monitoring subtle shifts. Optical sensors offer non-contact, sensitive detection. This Powered Tilt Sensor, with its infrared motion sensor, provides a detection distance of 5-8m and a 120° detection angle, focusing on motion rather than just static tilt. Its IP65 waterproof rating ensures suitability for home and garden security. The Gravity Sensor A gravity sensor, in the context of tilt and shake, is effectively a type of accelerometer. It works by detecting the force of gravity (1g) acting on the sensor. When the sensor is tilted, the orientation of this force relative to the sensor’s axes changes, which the sensor then interprets as an angle. For 'shake' detection, the sensor measures changes in acceleration beyond the constant pull of gravity. This Powered Tilt Sensor's infrared motion sensor primarily detects movement within its 5-8m range and 120° angle, rather than solely relying on gravity-induced tilt changes, although any significant tilt would trigger its alarm function.
