Efficient use of energy becomes more crucial when increase in the cost of energy is observed. Since energy management is required to define the amount of consumed energy in a specific period of time, utilization of Energy Meters is essential. It is possible to measure the consumed energy by using a simple energy meter. But sometimes the limited functionality of these meters restricts their area of...
The aim of this research is to design and implement a cost effective and yet flexible and powerful home security system using the GSM technology. A mobile based home security system is needed for the occupant's convenience and safety. The system is designed to detect burglary, leaking of harmful gas; smoke caused due to fire and after detecting suspicious activity it sends a alarm message to the owner...
This paper intends to develop a three phase Y-connected Brushless DC (BLDC) motor controller by using low cost PIC 18f4431 microcontroller. Unlike a brushed DC motor, the commutation of a BLDC motor is controlled electronically. To rotate the BLDC motor, the stator windings should be energized in a sequence so it is important to know the rotor position in order to understand which winding will be...
ATmega32 RISC microcontroller (RMCU) is very popular among the students, teachers, amateurs, engineers, scientists and hobbyists for building electronics projects. These designers, while developing their projects, wish to learn the architecture, instructions and interfacing of the RMCU but many of them remain outside of this opportunity due to unavailability of low-cost learning kits. There are learning...
ABSTRACT The 89S52 microcontroller (MCU) is very popular among the students, teachers, engineers, scientists and amateurs to build small and cost effective projects for learning purposes and or to incorporate it in a bigger project. In these projects, the chip remains in the system and occasionally need arises to change the program bytes of the code memory (flash) without removing the MCU from the...
