The energy crisis in India is one of the major problems. Transmission of an effective power, as well as power utilization of this power, is one of the major problems. The power factor is the hidden factor, which causes a great loss of electrical energy and also harms electrical tools. The power factor of changing load can be calculated and rewarded using the static method. So we need to find out the reasons of power loss and extend the power system. Due to industrialization, the employ of inductive load boosts and therefore power system losses its efficiency. So we need to improve the power factor with a suitable method. Nowadays, the embedded system is very much popular and most of the product are developed with microcontroller based embedded technology.
Android operated home automation using Bluetooth device is a good combination of mobile technology as well as the embedded system. The user can manage Home appliances using Android device by installing on his/her Android mobile phone to control different home appliances. The user can send control signals using that application. This project comprises a Bluetooth receiver, which is connected to the circuit and it has a decoder. This decoder sends a code for the individual signal sent by the user. Then the particular load connected to the circuit will be activated depending on the signal given. At the output side of this project, we have connected 5 relays and a buzzer as a load.
A 4 quadrant DC motor control operation is necessary for industrial as well as marketable applications. These applications need both driving and braking that means motoring and generating ability. Some of these applications comprise lifts, cranes, electric traction systems, engine test loading systems, and cable laying winders. The different quadrant processes drive the motor with usual as well as the turnaround of both voltage and currents so as to run as well as to crack the motor either in any directions. Let us discuss an Arduino board based 4 quadrant dc motor control operations in brief.
Automation system is mostly depending upon the power systems in industrial, residential or commercial, which needs remote controlling and monitoring. By employing wireless technologies, it is more competent to execute a suitable technology depending upon the requirements of the proposed system like speed, cost, and distance.
For distant controlling and monitoring of different loads and by means of efficient power usage through real time power spending with the help of a PC based graphical user interface application. The progress of technology equipments is becoming simpler and easier for us. Automated systems have more benefits over manual system. PC based electrical load controlled systems are highly reliable, precise and time conserving systems. They give number of features like rapid data storage, transfer data and data securities.
