function updateCount() {
        $.getJSON("@Url.Action("CurrentSensorData", "Report")", function (dataResponse) {

            var divTempHumData1 = $('#TempHumData1');

            $.each(dataResponse, function (i, item) {

                if (item.TagId == 'TempHum1') {
                    divTempHumData1.html("Temperature: " + item.Value1);
                    divTempHumData1.append("<br/>" + "   " + "Humidity: " + item.Value2);
                }

            });
        });
    }
    var timeoutId;
    $(document).ready(function () {
        updateCount();
        window.setInterval("updateCount()", 30000);
