The major goal of this project is to create a sensor system capable of detecting activity behind closed doors in healthcare environments, focusing on circumstances where healthcare professionals must be informed of potential tampering or obstacles. This device fills a major gap in patient safety and security by sending real-time notifications when movement or obstruction is detected within a 6-inch radius of a door, without depending on optical sensors. Given the importance of patient privacy and rapid reaction times in healthcare facilities, the suggested sensor would provide exact, reliable information regarding activities behind the door while maintaining the space's integrity.

The key objectives are to create a sensor that detects the presence of both individuals and items behind a door and alerts healthcare workers as needed. This will serve as a warning system, allowing an early reaction to potentially dangerous circumstances. The sensor will be installed directly onto or within the door, and recessed to prevent tampering. It will have an anti-ligature design, which is crucial for reducing abuse, especially in mental health settings. The gadget will also turn off automatically when the door is fully open to avoid needless notifications.

The benefits of this project extend to the broader engineering and healthcare communities by pushing the boundaries of non-optical sensing technology and incorporating advanced tamperproof designs. By utilizing infrared and radar technologies, the project enhances sensor capabilities in restricted spaces, addressing a crucial need for unobtrusive and effective safety measures in sensitive environments. This solution also provides a model for future designs that aim to balance high security and patient safety, with a clear focus on ease of use and integration into existing healthcare infrastructures.
