Abstract— Providing a security system for any electrical equipment has become a vital interest in which the latest technologies are being adopted to serve this purpose. University classrooms usually implement automatic door lock attached with a sensor to enable access into the classroom. The access door needs a more autonomous, integrated, and intelligent functionality to improve smart classroom’s usability. This work presents the development of a secure door lock system by utilizing Quick Response (QR) technology and Raspberry Pi processor for accessing the university laboratory or classroom where the authorized person will also be able to monitor who have accessed to the classroom or laboratory. The data logging system is developed to track the ingoing and outgoing activities when accessing the security door from the web-based website server. In this vein, the authorized individuals are only the ones who will get the permission to access the doors. This is a preliminary work to test the system’s functionality to be used for different properties and facilities such as office, classroom and laboratory. Based on the result and data collection, the testbed development has worked properly as an initial s

Abstract— The term used for networking of objects, equipment, vehicles, and other electronics device into the network for information exchange purpose is called Internet of Things (IoT). Nowadays, IoT is widely used for connecting device and collecting data information. Therefore, the use of IoT is very relevant for agriculture. The project is about smart agriculture system that is implemented with IoT. The system is combined with irrigation system in order to cope with the unpredictable weather in Malaysia. Raspberry Pi 4 Model B is used as the microcontroller of this system. DHT22 and soil moisture sensor is used to detect the temperature and humidity in surrounding and moisture level of the soil respectively where the output will be displayed on smartphone and computer. So, Smart Agriculture Systems using Internet of Things with Raspberry Pi brings a tremendous impact on the farmer’s working method. Plus, it will also bring a positive effect on the crop production in Malaysia. Where about 24.44% water savings rate in a year can be achieved when using IoT-based irrigation systems compared to traditional irrigation systems. This would save the expenditure for hiring workers and avoid water wastage in daily needs.

Abstract—with every enhancement in Internet in terms of speed and bandwidth, IOT (Internet Of things) is taking the market on a new node and knocking the door with new opportunities of inventions.This paper talks about an energy saving electrical device Surveillance and Control system based on IOT.A large amount of energy is consumed by lighting appliances, so making improved efficiency and quick fault detection is a significant challenge.In this work, two different model approaches is followed depending on the nature of application.For small areas or confined premises IEEE 802.11 wireless technology is used where all the appliances is connected to a common Wi-Fi network.In the second model like street lamp pole where number of appliances grows only in one direction, wired configuration is used to avoid range issue.

Abstract—Cultivation is the fundamental wellspring of pay of the general population in a nation like India adding up to 15-16% of the Gross domestic product of the nation. As per the financial overview of India 2018, around 55% of the number of inhabitants in India relies upon cultivating as their wellspring of occupation pay and time has come to acquaint a few changes with supplant those conventional cultivating rehearses with the development of money trims under computerized nursery utilizing IoT through remote sensors, actuators, microcontroller, raspberry pi, GSM module and associating links. In this paper, we have proposed a low cost greenhouse prototype model which can be afforded by the Indian farmers for the cultivation of cash crops such as saffron, vanilla, sugarcane, etc. and they can carry out the cultivation under this automated greenhouse thus improving their social, economic and financial condition by a great extent.

Abstract—This paper describes the prototype of the All Time Medicine and Health device for the use of every person in need of drugs or medical assistance. ATMAH comprises of an automatic medicine vending machine to dispense drugs as per a doctor’s prescription. The vending mechanism is controlled by the raspberry pi which is a single board computer and the second aspect of it is the online portal for a user to check his prescriptions, and for the doctor to generate an e- prescription. The device dispenses out the prescribed medicines by the doctor when the user credentials of patients are validated from the database. The online portal is built on two fronts - a webpage and an android application which are linked to the same database. The patient can view his details and prescriptions through the android application or webpage by logging in with appropriate credentials.

Abstract— Now-a-days, crime rates are increasing at an alarming rate due to theft cases. It is equally important to catch the thief to prevent theft. Most of the time, thief escapes due to delay in action taken by concerned authorities at that time. In this paper, we present the design of a security system which solves this problem. The proposed system is for Smart Door lock technique with Raspberry Pi using IoT and is done by integrating webcam and motion sensor with e-mail. Raspberry Pi operates and controls motion sensor and webcam for sensing and surveillance. For instance, whenever any motion is detected, the webcam streaming starts and Raspberry Pi device alerts the owner through an e-mail on his registered mail-id. Whenever it is a wrong or random PIN entered, webcam captures the intruder’s image and sends it over e-mail for real-time action to be taken by the owner to prevent theft.

Abstract—- In water supply networks system, the major problem is water leakage. Unwanted water leakage due to leaky pipe lines and beneath the underground pipelines is almost always pertaining in drinking water supply networks. This system contains two sections, first part is leakage detection and automatically closes the solenoid valve for to prevent the over leakage of water and send SMS to the corporation using GSM module according to sensor information. By using GPS location to detect where the leakage takes place. The second part is that to fill the water tank by using android application.

Abstract—Autonomous miniature vehicles are widely used to test many types of algorithms and simulate the driving behavior as in the real world. In the last decade, several approaches have been proposed for obstacle avoidance in self-driving vehicles. In this paper, we present our autonomous vehicle implementation which gives a solid solution to this problem in an efficient manner, using a Raspberry Pi and a LIDAR module for indoor navigation. Our vehicle is capable of navigating in an unknown environment while avoiding obstacles. Unlike other implementations, our vehicle doesn’t use Computer Vision (CV) techniques for obstacle detection but only a single LIDAR sensor and thus can safely navigate in low luminosity enviroments. We perfomed various experiments and verified the success of our implementation.

Abstract—Environmental monitoring systems are often designed to measure and log the current status of an environment or to establish trends in environmental parameters. In this paper, We proposed an autonomous robotic system that is designed and implemented to monitor environmental parameters such as temperature, humidity, air quality, and harmful gas concentration. The robot has GPS coordinates, and it can store data on the ThingSpeak IoT platform. The mobile robot is controlled by a smartphone which runs an app built on the Android platform. The whole system is realized using a cost-effective ARM-based embedded system called Arduino and Raspberry Pi which communicates through a wireless network to the IoT platform, where data are stored, processed and can be accessed using a computer or any smart device from anywhere. The system can update sensor data to IoT server every 15 seconds. The stored data can be used for further analysis of the reduction of pollution, save energy and provide an overall living environment enhancement. The robotic system has designed for cost effective remote monitoring environmental parameters without any human intervention to avoid health risk efficiently. A proof-of-concept prototype has been developed to illustrate the effectiveness of the proposed system
