BirdSense is a non-lethal bird deterrent device that uses a PIR motion sensor to detect bird movement and triggers a thud sound via a speaker to scare the bird away. Non-invasive alternative to bird nets Housed in a compact MDF box, placed on balcony railings Designed using laser cutting and simple electronic circuitry Accurate detection achieved by tweaking the sensor’s field of vision using a plastic layer Effectively reduced false positives caused by moving branches  

Constraints Must not create a fire hazard Should not cause structural damage to ceilings or rooftops Must not cause physical harm to birds Should be easy to install and maintain Idea Brainstorming Prototypes Reflective Window Surface: To disorient approaching birds using reflected light. Hawk Dummy with Alarm Sound: A scarecrow approach that mimics predator presence. Final Prototype MDF box design via laser cutting PIR sensor with tuned detection range Speaker buzzer activated on detection Achieved zero false detections during testing Skills Applied CAD Electronics Design Thinking Programming Soldering Prototyping Laser Cutting
