Insafe
Portable Smart Device
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.
​
​Alert System
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.
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 provides a capacity sensor and a similar set with the code, tried the coding and electrical components for the rough prototype. Created multiple mock-ups using different form factors to test out which fits on the door handle and which is user-friendly.
