Analysis of the eyelid movement enables doctors to diagnose several types of
neurological and ophthalmic diseases.
The project's goal is to connect the device to the AWS cloud services and create an easy to use
web page that connects to the AWS cloud, and control the device from the web page.
Using small and light magnets, attached to the eyelids of the client, and magnetic sensors attached to glasses, we can gather information about the eyelids movement. Eyelid’s movement results in movement of the small attached magnets and therefore a change in the magnetic fields that is being measured by the magnetic sensors.
The project’s goal is to take a ready to user device and transform it into an IoT device, that accurately collects information on the eyelid’s movement for few minutes and in the end, move the measured data through Wi-Fi to AWS cloud, the device is controlled by a webpage which sends requests to the ESP
and receives data through AWS services and the ESP receives the requests from the AWS and acts.
Also the ability for the user to view the data in a plot graph and interact with it.
The magnetic sensors measure the magnetic field in the three axes and in a rate higher than 1 kHz (for all the sensors together). The duration
of the whole measurement should be around fifteen minutes. During this time, the data is transferred from the sensors to the SD card.
The system includes a micro controller (ESP8266), four magnetic sensors (TLV493D), SD card, battery holder (for rechargeable AAA batteries)
and a DC to DC converter. There are additional resistors, capacitors, LEDs and a shift register in order to create the working points and help to operate the system.
