The designing of the solar panels at the top of the bus is calculated by three major steps, 1) The calculation is done for electrical energy demand of air conditioner in bus by using thermodynamic temperature flow inside the bus, with respect to the minimum and maximum temperature data for Chennai city during year 2008. 2) The calculation is done for monthly energy produced by single chosen solar panel using the solar radiation data for Chennai. 3) Internal Electrical circuit is designed for the bus by choosing the specific MPPT solar charge controller and battery for storage. All the calculation are done using MAT LAB.
Intelligent Ventilation System(IVS) is an environment friendly product for BTS rooms. In the era of electricity crisis, this Microcontroller based control system not only reduces the consumption of power in BTS rooms but also minimizes the emission of Carbon-di-Oxide from Air Conditioner(AC)of a BTS room. The whole controlling is done in this project by a PIC Microcontroller IC 16F877A. So IVS is a Microcontroller based electronics device that maintains the overall environment of a BTS room by controlling a Fan unit, a Filter unit and an AC by observing the room temperature, room humidity and battery voltage level of a BTS room.
