 var app = angular.module('PIR_Detection', []);
    app.controller('myCtrl', function ($scope, $http, $window) {
        $scope.sel_val = 0;
        $scope.DefaultLabel = "Loading.....";
        var post = $http({
            method: "get",
            url: "../data.json",
            dataType: 'json',
            data: {},
            headers: { "Content-Type": "application/json" }
        });
        post.success(function (data, status) {
            $scope.Customers = data;
        });
        post.error(function (data, status) {
        });

        $scope.getPIRData = function (id) {
            var url = "/PIRDetails/GetPIRStatus/" + id;


            $http.get(url)
                .then(function (response) {
                    $scope.myWelcome = response.data;
                    $scope.pirstatus = base64toHEX($scope.myWelcome.dataFrame);
                    $scope.timestamp = getIST (response.data.timestamp);
                    $scope.rssi = response.data.rssi;
                    deviceid = id;

                });
        };
        setInterval(function () {
            $scope.getPIRData("100010102");//unable to pass id here
        }, 30000) 

});

you can do it in various way,

example:

//set data
window.deviceId=Id

and use it in settimout

setInterval(function () {
            $scope.getPIRData(window.deviceId);//unable to pass id here
        }, 30000)

but you can declare any global variable of the settimeout outer scope, then that variable will be available into the settimeout call back function, because then it will be treated as Closures

Courtesy of @tvanfosson:

You probably want to have a function that creates the interval timer for you. Pass in the parameter to the function so its value is captured in the function closure and retained for when the timer expires. 

function createInterval(f,dynamicParameter,interval) { setInterval(function() { f(dynamicParameter); }, interval); }

Then call it as createInterval(funca,dynamicValue,500); Obviously you can extend this for more than one parameter. And, please, use more descriptive variable names. :)
