Solar Powered Cooling System of Deep Freezer Using DC Compressor ( Click to open/close project tabs )

This project is aimed to incorporate solar power in freezing system for farming, hospitals and household in rural areas. We have designed a system that will allow connecting the solar module with the deep freezer through DC compressor. In off-grid places of Bangladesh storing the harvested crops is a major problem. Most of the crops get rotten by the time they reach to local market. Moreover, it consumes a lot of electricity for storing these crops in the grid supported area. Keeping these problems in consideration this project focus on powering the deep freezer with solar electric system supported by battery and charge controller and testing the performance -at BRAC University premises. Based on the result further extension will be one for large scale implementation.

Digitalization and Development of Torque Sensor Based Control System
and Implementation in a Microcontroller ( Click to open/close project tabs )

As we are living in an advanced modernized world, a huge number of populations appreciate to work within a comfort zone, provided with more efficiency with the aid of better technology. We know human labor is required in almost every vehicle and in some mechanical job this effort is quite extreme to produce the start up power. In some cases, continuous effort is necessary. This research and development project will emphasize the terms that will lessen any excess of human labor through a torque sensor controlling system by detecting the excess power delivered by human and then assisting him in his effort with devices such as motor, etc. This will save energy as only renewable energy resources such as solar power will be used for fuel power to limit overuse of human effort. Torque sensor will be used to indicate the need of assistance felt by the labor at a particular time. As previous work has already been done on this basis, this research is taken under consideration in search of finding alternative methods to enhance the efficiency in assistive power. Moreover, the findings are to be implemented in micro-controllers for commercial purposes and can be modified appropriately for extensive uses in different sections.
