Fly Guardian is a device for sensing your pant zipper When the zipper stays down for more than a certain number of minutes, it communicates with an internet server and sends a text message to the user, informing them to ‘zip it up’ and prevent an embarrassing situation.

Fly Guardian is an Arduino based device, installed on the buckle on the belt and another piece on the zipper to detect the status of the zipper. Through bluetooth it sends a signal to the computer and connects to the server if the zipper is down. Then the server is going to send text message to the user through one of the online text message services.
