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.

//COMPLETE WITH RFID/NFC INTRO

Usage instructions

Our supported build platform is mbedOS online compiler.

For detailed instructions on how to setup the board for AWS IoT Core follow this link. That also includes instructions for the board Wi-Fi module setup.

The custom message that will be pushed to AWS endpoint has to be specified here between the two double apices in main.cpp file.

char payload[] = "{ \"payload\": TWITTER-ID-GOES-HERE }";

In our case, it's a JSON message containing a field named payload with a Twitter ID valued associated.
