            An ng-paste is a custom directive to user expectation base. This directive very useful to real time development. Here i share some real experience for myself, we develop a online question and answer program exam event.  

           This application is not include copy and paste restriction for any piece of code from the exam event, But we analysis the user is using any copy paste piece of code from the question and answers means we get flag value. How we get a flag value is using ng-paste directive is listen the paste event flag value. This value is send to server and analysis how user response to genuine.

AngularJS:

var app = angular.module('PasteApp',[]);
app.controller('PasteCtrl', function($scope){
$scope.paste = false;
}) ;

HTML:

<div ng-app="PasteApp">
<div ng-controller="PasteCtrl">

In the earth who are live plants, animals and human beings have some basic sensing behavior by nature, so those approaches and behaviors we fallowed and implement to nonliving things. These are the major behavior we identify from the sensors like light, sound, motion, temperature, pressure, acceleration, position, Object presence, and Air. Here I'm sharing few components 1. Temperature Sensor Temperature sensor sensing the circumstance of temperature in the installed places. 2. Ultrasonics Sensor Using ultrasonic to identify the obstacle distance in front of the device and based on the data we can manipulate the application. 3. Pressure Sensor Find the pressure value on the device to you gave the pressure on it. 4.
