## Article

## **Proof of Concept Door Alarm**

This project is an example of Ethernet shield.
User can monitor sensors easily by using Arduino platform through Cloud.
This project would be included in Cloud category of WIZnet Museum.

Hardware components:

-. Arduino UNO & Genuino UNO

-. Arduino Ethernet Shield

-. ttp223 sensor

Software apps and online services:

-. Cayenne

-. Arduino IDE

## **Story**

A first project using the Cayenne Android App. A proof of concept of an alarm than notifies me via email when a door is opened. Still needs to be set up to be battery powered but the concept works.

The capacitive touch sensor is attached to digital pin 2 of the Arduino and Cayenne reads that input and inverts it. When the door is closed the magnet is near enough to the capacitive touch sensor to give a logic high level. This is inverted by Cayenne so while the door is closed, cayenne outputs a 0. When the door is opened, the magnet moves away from the sensor, the capacitive touch sensor outputs a 0, so cayenne outputs a 1 and triggers the notification.

Without the Cayenne App this project would’ve taken much longer.
