$(document).ready(function() {
    $("#download").click(function() {
        var count = 0;
        if ($('#temperature').prop('checked')) count++;
        if ($('#illuminance').prop('checked')) count++;
        if ($('#button-state').prop('checked')) count++;
        if (count > 1) {
            window.location.href ='https://api.thingspeak.com/channels/899906/feeds.csv?start=2019-11-12%2019:11:12&end=2019-11-13%2019:11:13';
        }
    });
});
