Code

detector

This component allows DISCO-L475VG-IOT01A board running mbedOS to enstablish an MQTT connection to your AWS IoT Core and to publish data every time a simple magnetic sensor detects high impedence case on the circuit. The goal is reached by checking the integer value returned by the sensor connected to a digital pin (in our case the D1 pin, we could obviously use any of the board's digital pins to do that). Also a led is turned on, it could be replaced by a sound alert, every time the door is open.

notifier

Python-based component sending a notification to the user's Twitter account, using TwitterAPI, AWS Lambda and AWS Iot Core
