A woman going through menopause often experiences hot flashes and heart palpitations due to changing estrogen levels. It can cause a heart rate to increase by 8 to 16 beats along with sweating and red skin.
To solve the problem of hot flashes, My Heartbeat uses real time heart beat data from Fitbit to detect irregular heartbeats. It then automatically turns on a fan to cool the user down when she is experiencing night sweats. It uses Alexa, a WeMo switch, and Fitbit data to analyze heart rate and switch on the fan programmatically.
The platform tracks beats per minute from Fitbit intraday data. If an elevated heart rate is detected and that is abnormal, the application will alert the user through any Amazon Echo device. It can analyze a user's heartbeat and get the average heart rate over a time series.
Symptoms My Heartbeat Solves
Hot flashes
- This application helps users suffering from hot flashes by cooling them down with an automated fan.
Irregular heartbeats
- The application alerts users through any Amazon echo device if they are experiencing irregular heartbeats.
The application is available at https://damp-gorge-66037.herokuapp.com/
Start Fan
JavaScriptThis is a GET call that uses a virtual button to an Amazon Alexa routine to turn on the fan which is connected to a WeMo switch.
function startFan(){
var ACCESS_CODE = JSON.parse('<%- accessCode %>');
var xhr = new XMLHttpRequest();
var url = "https://api.virtualbuttons.com/v1?virtualButton=1&accessCode=" + ACCESS_CODE;
xhr.onreadystatechange = function () {
if (this.readyState != 4) return;
if (this.status == 200) {
var data = JSON.parse(this.responseText);
}
};
xhr.open('GET', url, true);
xhr.send();
}
