Use Cases

This sensor finds application in residential security systems for monitoring entry points, detecting unauthorised access through doors and windows. The tilt measurement capability specifically addresses complex window types that incorporate both tilting and turning mechanisms, common in modern European fenestration systems. Automation enthusiasts benefit from the light sensing feature, enabling intelligent lighting control based on natural light levels and room access patterns. Commercial implementations include occupancy monitoring in office environments and access control verification in retail settings.

The device serves elderly care applications by providing discreet monitoring of movement patterns, while parental control scenarios utilise the sensor for monitoring children's room access. Integration with home automation platforms enables sophisticated conditional responses, such as activating ventilation systems when windows open or adjusting heating outputs when access points remain ajar during colder months.
