Mailbox Notifier

By ,

This smart mailbox sensor prototype was contract work for a client.  I was approached to work on a connected mailbox notifier that would inform the user not only when mailbox is opened, but whether mail was added or taken away.  I determined feasibility by researching possible sensors.  Once a sensor was identified, I designed the electronics and developed the firmware for the first prototype using Particle development boards.  I also designed the mobile app and the backend using OpenHAB.  The logo, image, and video below are copyright of George Gruber.
