Clean and Green Technology

We live in an era of skyscrapers. The maintenance has always been a tedious, uneconomical, unsafe task, which is performed only by professionals. These problems in the present scenario, made a necessity of a product like PLECO, as the famous saying goes “necessity is mother of invention. Pleco is totally unmanned, economical, environmental friendly, safe, smart, viable product which is used in grooming the skyscrapers effectively. On an average a building like U. B city spends approximately around 4 lakhs for cleaning only the glasses each time. Pleco can perform the same tasks at 0.0025% of the amount spent previously (aprox 1-1.5 k) and safe as no human involvement is need at higher altitudes of the building. The design is such that it performs skill based tasks like foam washing, dirt removal, polishing and many more, by climbing the walls with a working range of more than one kilo meter. Pleco sticks to the wall using suction or adhesion created by ducted fans (4500kv). It can also be controlled manually using N. R. F aurdino nano rc receiver transmitter circuits in case of emergency. The product is designed in such a manner that it automatically gets charged when it reaches certain threshold voltage, in the nearest station installed at every floor. At the first stage the brushes rotate and remove the dirt accumulated on the glass. It remains still for a longer time at the places where the dirct accumulation is more so that it cleans it better. Hence the reflected ir rays will slightly vary in magnitude, if the dirt concentration is less, then the glass appears semi transparent hence only little amount of ir rays is reflected back. In such places the product will move smoothly without delay.With safety as our theme, the risk and danger for the labors life working at higher altitudes is precluded.

Throughout India, the accumulation of waste and trash in public places is a problem that needs to be addressed. Picking up and sorting garbage is a tedious task and has health effects on the people who handle the waste. To overcome this problem, a robot that seeks and picks up garbage from the public places and also segregates them into metallic, dry and wet waste has been proposed. The proposed robot can put an end to accumulation of trash in public places and also improve waste management. Swachh Bharat Abhiyaan for a “Cleaner & Hygienic” India is the main motivation behind taking up this project. This project aims to reduce the human effort involved in picking up and segregating the waste (into dry, wet and metallic) by using Trashbot (a garbage seeking and segregating robot). Low -level waste management practices are now undergoing rapid change such that the technology and requirements for waste segregation in the near future may differ significantly from those of the present day. Trashbot is a project still in its relative infancy. With its main motto “Cleanliness and Hygiene”, the robot has the capability to establish itself as a product that could not only clean the surroundings, but also aid the processes of waste management.

In present busy life, rechargeable batteries of electronic gadgets like smart phones & laptops drain faster due to excessive usage and it is difficult to recharge them on the go. More over everybody cannot afford an additional battery source / Pack. We are designing a modern smart bench which absorbs the abundantly available natural photovoltaic green energy in DC form and store it in a Battery pack. This energy is converted it to AC form as and when required, for utilization. The smart bench also offers lighting system in addition to charging source. The bench is designed to offer a comfortable seating accommodation for four persons for quick relaxation while charging the devices. It is a smart-designed bench that enables all people to charge their devices. Anyone can relax on this bench, enjoy 4G Internet and simultaneously charge their phone or tablet. It functions solely on clean solar energy; this energy gets stored and is available to you 24/7. Working, studying, or just relaxing, it can all be done on this modern bench that features both wireless chargers and USB ports.

As we have seen during the pandemic, vaccine storage has been very challenging, therefore we need efficient vaccine storage systems. Frequent or long-duration power outages that use grid-powered cooling are impractical for vaccine storage. This is a serious challenge that threatens the continuity of the vaccine cold chain, especially in remote areas. the “Peltier cooling module” which works on thermoelectric refrigeration, aims to provide cooling by using thermoelectric effects rather than the more prevalent conventional methods like ‘vapor compression cycle’ or the ‘vapor absorption cycle’. There are three types of thermoelectric effect: Seebeck effect, Peltier effect, Thomson effect. Peltier refrigerator works on the Peltier effect which states that when voltage is applied across two junctions of dissimilar electrical conductors, heat is absorbed from one junction, and heat is rejected at another junction. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump that transfers heat from one side of the device to the other, with the consumption of electric energy, depending on the direction of the current. Such an instrument is also called a Peltier device. It can be used either for heating or cooling, although in practice the main application is cooling.

Water management and safe sanitation are key challenges in today’s world, and efforts are being made to overcome this challenge. In order to avoid water crisis, we should design and contribute to innovative and life changing products which will help billions of people lead a healthy lifestyle. Automatic faucets have the advantage of shutting off automatically after washing hand, thereby reducing wastage of water. There is a necessity to develop a smart faucet that monitors water consumption and is detachable, affordable, and hygienic and user friendly. This project aims at developing an embedded system, ‘Detachable Smart Faucet’ that monitors and controls the water flow through faucets and uploads the water consumption data to a database that is accessible by the user. The smart faucets presently available in market are quite expensive and are easily not affordable. Also the entire existing tap setup has to be changed in order to install the automatic faucet which incurs additional cost. The proposed design overcomes these drawbacks and provides additional features.

Waste management is becoming a hot topic in policy circles. Municipal governments, which are largely responsible for building and maintaining waste disposal networks, are keen to find ways of minimizing the cost of disposing of waste and the sheer amount of waste society products. Exposure to various hazardous wastes can affect human health, children being vulnerable to the pollutants. Direct dumping of untreated waste in rivers, seas, and lakes results in the accumulation of toxic substances in the food chain through the plants and animals that feed on it. The main objective of this project is to design a system using Arm Cortex LPC2148 microcontroller for automatic segregating of waste at source and capable of cleaning. This project aims to design an automatic segregator bin which can segregate the waste at source that helps in reducing the time taken for processing, and segregation work done for large amounts of waste in the later stages. It includes different partitions for collection of different wastes using sensors, with a LCD display which updates the status of the bin. The bin uses a vacuum cleaning mechanism for cleaning purpose. The system uses IR sensor for obstacle detection. Moisture sensor is used to detect wet materials or wet wastes containing moisture elements. Metal sensor is used to detect the metal based on relay, i.e. if any metal waste is placed near to metal detector, the relay is turned on. It is based on the principle of Electromagnetic induction. LCD display is used to display the status of the bin. Ultrasonic sensor estimates the distance of the obstacles in the front and sends message saying if the bin is full or not through GSM. This bin can be useful at places like offices, apartments, shopping malls etc. this system will be useful in making Waste Management in smart cities automated.

India is facing water crisis and it is necessary to critically consider approaches to treat water so that it is suitable for use. The Proposed method of water treatment aims to remove pollutants from the water. Reverse osmosis is one of the oldest and most popular separation techniques used mainly for the purification of water. The process was mainly adopted for desalination of seawater in the year 1950, where the whole process was relatively slow and limited to certain laboratories. While reverse osmosis technology is one of humanity’s important scientific innovations, we will develop a basic understanding of the whole process here on this page. It works by forcing water through a special fine membrane to eliminate impurities that may not be visible to the naked eye. These membranes remove impurities based on their size and shape. This means that particles larger than water molecules cannot pass through the filter. The membrane blocks harmful chemicals and contaminants such as pesticides, viruses, microorganisms, ions, and bacteria, amongst others.

This work focuses on efficiently managing an agricultural field without human intervention by making the use of an IoT-based system. The principle concept used here is, electrical conductivity of the moisture is present in the soil. This setup includes a servomotor which is used to regulate the water flow, based on the input from the option selected by the user on the webpage pertaining to the type of soil and the corresponding crop. The input is generated from the webserver hosted on the microprocessor which is further then processed to the microcontroller based on the temperature of the surroundings. The PIR sensor is used to ensure the security of the agricultural field.

Human Energy Harnessing is the process of extraction of energy from human beings using physical work. One of the processes used to achieve this is the Pedal Power Generation. This technology harnesses energy from power exerted from pedaling a bicycle and can be used to generate electricity or operate mechanical devices. Thus considerable amount of energy while pedaling can be harvested effectively using simple battery charging circuits. The main aim of the pedalite project is to design a source of lighting that is reliable and durable and can be used to light up homes or schools in areas that are un electrified. The objective of the project is to design a non-conventional, electro-mechanical based energy storage system. To generate and save power as well as motivate people to maintain a healthy life. To electrify the parts of the country which still have no access to electricity, switch over to battery driven bicycle or normal mode of transportation. This is the best way of power generation having less environmental impact. In this project human energy is used as the source to generate power by pedaling bicycle, which in-turn gives mechanical energy and this mechanical energy is converted into electricity through permanent magnet DC generator.
