This is a simple mailbag watcher that notifies you if you have new mails in our postbag.
Its based on the Omega2 which sends a push notification over the wifi.
It uses classic 555 timer to switch on the power if the reed sensor on the postbag is detecting some new mails.
Please checkout the Project documentation on my github page!
NOTE :This is a fastbuild project it took only 3 hours to build this and its not very clean :)
