VEHICLE THEFT DETECTION AND SECURE SYSTEM USING ARDUINO

Today vehicles form an important asset to us, without which our life would be incomplete. But, when it comes to the security of our vehicles, we are very helpless. It is of a great concern, especially in metropolitan cities, where these incidents occur each and every day. So, in this paper, we have focussed on the security of vehicles. The Aim of this work is to authenticate and inform the details of the vehicle to the owner through SMS when it is to be used by any other person. If the owner is aware of that person he can give access through a return reply- motor on otherwise he can deny by replying –motor off. This is possible using GSM and fingerprint sensor. In case if the vehicle is theft by any chance, we can detect the vehicle using RFID reader where RFID reader is placed in the device. On the other hand the owner can also trace the location of the vehicle where he gets the information in terms of latitude and longitude using GPS. All these operations are controlled using ATMEGA328 micro controller. Keywords: Arduino, GSM, GPS, RFID, Fingerprint Sensor, Node mcu.

To overcome this issue, our proposed idea utilizes RSSI (Received Signal Strength Identification). Node MCU acts as a receiver and the server acts as a transmitter. Node MCU has an inbuilt Wi-Fi (ESP-8266) module. It receives the signal and estimates its strength based on which ambulance arrival is predicted. This alerts the other vehicles and their speed is also controlled. In addition to this, RFID technology is used to change the adjacent traffic signals to red, thereby providing pathway to the emergency vehicle.

VISUAL ACUITY CHECK

Visual Acuity check is the test initiated to examine patients' potential eyesight problems. After detection, it is then rectified under the guidance of a professional (ophthalmologist) with appropriate solutions. This test usually includes expensive instruments which make the setup bulky and immobile. Due to the limited resources and high cost, people residing in remote areas do not prefer to undergo this test which makes them ignorant concerning their visual health. So, to turn their attention towards visual health and help them avail this test, we are trying to propose a set-up namely Visual Acuity Check with minimum instruments. The key components of this setup are a standard Snellen Chart, a system that uses a Speech-to-text converter, and a node MCU for remote automation. This system includes pre-defined standard formulae and conversions for diopter calculations. This test does not necessarily require any professional handling. Thus, this movable setup will offer high efficiency at a very low cost. Key Words: Snellen chart, Node MCU Module, speech to text converter system.

It was also found that the accuracy rate would increase if the flow rate were set for a short period, while the accuracy rate would decrease if the flow rate were set for a long time. The experiment revealed that the developed prototype system could monitor, alert, and automatically control the flow rate of saline administration to patients as the specified objectives.

Smart Energy Grid using IOT

Abstract: With increase in population and infrastructure, need for energy production is gradually increasing and to full fill the demanding needs of consumers is in organization hands. This brings the issue of energy production and energy distribution for the organization. Existing meters are not so consumer friendly and always need a periodic checking from utility to inform about their monthly tariff, which requires more man power and is a time consuming process. Also the organization is not able to maintain proper record of consumer data. This project aims to reduce this burden and it makes a real time observation of energy consumption for the consumer as well as the organization. The consumer as well as the organization is able to monitor the real time usage of energy and receive notification to their mobile or on organization website. Also, it notifies the consumer about the peak hours and the grid is able to monitor their geographical area. This project involves Node MCU as main controller and for internet communication and sending real time data over internet, current and voltage sensors.
