The growth of mobile digital communication devices has seen a corresponding growth in the data created by users in the course of their mobile communications. The ease with which such data - including sensitive time-dependent location information - can be collected and stored raises clear data protection and concerns. The value such data offers to both law enforcement agencies and the private sector has complicated regulatory responses to such data protection concerns. This has lead to the contradictory situation in which mobile data is used by the law enforcement agencies and the private sector to identify individual users, yet this same information is not considered to be 'personal data'.

In modern day’s high tech world, all of us are constantly experiencing EM radiation from almost all sources. Each and every source introduce its own EMF. At this very moment as you are reading this paper, you are probably being exposed to many electro-magnetic fields. The situation is no different while we are at play, travelling, at work, reposing at home, and even sleeping on bed. Practically there is an increase in EMR pollution with the increase in every new invention. EMR of all frequencies serve as one of the fastest growing and most common environmental impacts, about which speculation and anxiety are growing. The digital communication devices which we use emit digital pulsed radio-frequency EMFs which are perhaps one of the most harmful kind for human health. In today’s world use of cell phone has become ubiquitous with an estimated subscription of 6.9 billion globally. In modern day telecommunication cell phones play a very crucial role. It is not astonishing that the level of invisible electromagnetic pollution on our planet is tremendously high. As a result it is essential to examine, discern and check any possible impact on public health. The leading aim of this paper is to examine the harmful impacts of the electromagnetic radiation, survey the regulations which are in place to keep a check on the levels of radiations and to suggest a few daily habits which will help to reduce one’s exposure to such harmful radiations..


Once upon a time, India is rich in vegetation and agriculture. Now, the current scenario is totally different. Every Indian has been trained to work in different fields. In our day to day life, water has increased its demands in overall world which results in water scarcity. This kind of factors affects the regular plantation fields and home gardening. In this connection, we have proposed a methodology to overcome this problem. In the proposed research, a kit with probes and sensors is developed to measure the moisture and humidity level of plants in order to ensure the required water quantity. A solenoid valve is controlled through automation by pre-setting the values of moisture. If the moisture level goes down below certain value, then the solenoid valve is set to open and the water flows. On keeping the sensors on the top of the soil would not sense the parameters effectively which leads to unreliable results. So, in our suggested 0technique, the sensors are placed just below the soil surface, which is nearby closer to the roots of the plant, for getting the significant outcomes. The humidity sensor measures the humidity present in the air and indicates the probability of rain. This feature helps the farmers and the other gardeners in their routine work. This leads to make our country as green and rich in agriculture. There are two more sensors used viz., the flow sensor for measuring the flow rate as well as the volume of water used and the ultrasonic sensor for measuring the water level in the tank for control purpose. The sensors’ data can be communicated to the remotely located user through digital communication devices such as NodeMCU (Arduino) and Internet of Things - Blynk platform.
