Insafe is a portable smart device designed to enhance security in shared spaces like Airbnb or hotels.
It hangs on the inside door handle, where its metal components detect electrical currents.
Unusual activity triggers alarms and flashing lights, potentially deterring intruders. It can also send alerts via calls or emails if you're away.
InSafe identifies unauthorized handle attempts, thanks to Adafruit electronics and Arduino programming. Successful tests confirm its effectiveness in ensuring security and peace of mind in shared environments, providing a preemptive alert system for individuals and their belongings.

Validation
Put Insafe on different door handle to test out the radius and thickness of the mock up. To make sure the triangle shape can fit different handle, easy to put on & take out.
Capacitive Sensor
To distinguish intruders, normal visitors knock while avoiding the door handle, whereas intruders touch the handle, transmitting capacitance through it. This device triggers an alarm if the capacitance exceeds the average, signaling a potential security threat.
Coding
Arduino platform provide capacity sensor and similar set with the code, tried the coding and electrical components for rough prototype. Created multiple mock up by different form factor to test out which one fits on the door handle and which one is user friendly.
It hangs on the inside door handle, where its metal components detect electrical currents.
The metal components of InSafe come into contact with the door handle, collecting electrical currents.
When there is an abnormal electrical current, it will alert you by sounding an alarm and flashing lights, potentially deterring intruders who haven't entered the room yet.
It can also send alerts through phone calls or emails to notify you if you're not at home.
