  • Energy harvesting using IR LED array

IR (Infrared) led array generates power when subjected to concentrated light. This behavior is based on the principle of reverse electroluminescence effect of semiconductor element. Electroluminescence is the phenomenon in which a material emits light in response to the passage of an electric current or strong electric field. Reverse of this phenomenon is the principle used in the proposed work.

It has been observed that the output voltage depends upon the number of IR LEDs and the distance IR LED array from the light source. The voltage has been recorded by varying each parameter. It has been observed that two star shaped arrangements connected together serially give maximum output voltage. It has been observed that output voltage is directly proportional to the number of IR LEDs, inversely proportional to distance of IR LED array from the light source.

  • Piezoelectric Energy Harvesting System Using Cantilever

Piezoelectric energy harvester consists of two cantilevers on which piezoelectric patches were bonded on both the sides and electrically connected in series. A cantilever beam type of structure with 3-1 loading mode has been chosen because of its simple structure.

  • Piezoelectric Energy Harvesting System Using Rotatory Motion of Fan

Energy harvesting system using fan works on the principle of piezoelectricity, which says if a mechanical force is applied on piezoelectric material, it will generate potential difference. In the proposed work, rotational motion of fan disc is converted into the translatory motion using a mechanism. Rod attached to the fan disc will hit the piezo disc as fan rotates. The crest-trough pattern designed over fan disc is responsible for translatory motion of rod. Output voltage obtained is AC in nature, so for storage purpose it needs to be converted into DC which requires a rectifier circuit. The proposed design generated a maximum output voltage of 9.2V and a maximum current of 107uA .

SmartSwitch is a home automation system which uses the general  purpose microcontroller

It can control the electrical appliances of low and high power requirements through a computer or smartphone application. These appliances can be controlled through a local home network and internet from anywhere across the globe. Both these options can be both wired and wireless depending on the type of network the user hasd.  It also has an ability to save the state of which device was last on or off and resume from that state in case of any power failure.

  1. URJA RATH (Solar E-Rickshaw)

 While researching about the various initiatives and projects by government as well as private sector in the domain of solar powered vehicles for our project we came across new delhi based Urjaglobals initiative of a solar powered vehicle the UrjaRath. The initiative being quite similar to our problem statement was looked into. But because of certain problems the initiative of urja global could not be completed. So to continue in that field we chose to keep the name urjarath which signifies the incomplete attempt of the firm.

The Indian scenario has for long been associated with cycle rickshaws. But these are slow as a mode of transport, require too much effort form the rickshaw puller and are also not an efficient solution. Therefore, the e rickshaws were introduced which provided speed at a better cost and were also easy on the part of the rickshaw pullers.  But the e rickshaws are still a costly option at Rs 1.25 lakh for the poor rickshaw puller. So the need of the hour was another solution which overcomes all these problems.  Also  with the increasing global energy crisis and environment issues for saving electricity an energy friendly alternative was thought of and thus the UrjaRath which is a solar powered budget friendly alternative took it’s shape

Energy harvesting utilizes naturally occurring sources of energy and converts them into forms that can be utilized in the normal ways. It finds its application in wearable electronics, where energy harvesting devices can power or recharge cell phones, mobile computers, radio communication equipment, etc. Energy is scavenged from the walking process using piezoelectric stacks and to use this to transmit a GPS signal and to determine the location of the person.

Sufficient amount of power is produced to transmit a RF signal. A high voltage and low current signal is produced using piezoelectric material which when regulated can be used for various low energy applications.

A timer based water controlling system was designed to overcome the water wastage problem using real time clock (RTC) and Arduino as the controller. Further a relay module and voltage regulators are used to operate solenoid valve (actuating mechanism).

A cost effective and simple solution to the problem posed by PGI’s officials. First of All the controller was decided for the purpose. Appropriate hardware was designed and selected based on its availability and simplicity. The codes were burned in the controller which is specific to its operation.

A digital control system can be provided and an intelligent monitoring system can be created which will deliver precise monitoring and creates usage and consumption statistics that help to optimize settings.

The project aims at measuring rpm of rotating machines in real-time and varying its average rpm, α, ω, ϴ as per requirement.

Initially, the real-time data corresponding to current rpm will be acquired. Average rpm, α, ω, ϴ will then be calculated and computed with the help of received data. Above mentioned parameters will also be displayed graphically for better visualisation. The user is then allowed to change the parameters wirelessly or through remote.
