Day 13: Alarm system with push messages
Today’s project deals with a simple silent alarm system with password input for resetting the alarm. So that you get anything at all from the alarm, the board sends a push message to your smartphone. We’ll set the tilt sensor that’s behind today’s door as a motion detector. It can give information about vibrations and thus inform you if someone tips the NanoESP board.
The Blynk interface for today’s project is kept quite simple. There is a terminal through which the important information is delivered. At the same time, the terminal is used to input the password. Set the password in the programme. If you haven’t entered anything, the password is “password”. There’s also another element, namely the push widget. Push messages are sent through it to your mobile. Push means that the message appears directly as a message on your smartphone. In the widget, you can choose between “Normal” and “High Priority.” With High Priority, the message is displayed immediately, but it needs significantly more battery. Now if someone tries to steal your NanoESP, you’ll get a message directly on your mobile.
