Automatic Control and Monitoring of Electrical Energy Consumption Using PIR Sensor Module

Low power consumption is a very good advantage in this energy hungry world. A microcontroller-based Automatic Light Control is designed and constructed to save the usage of electrical energy and to avoid wastage using a room as a study. This project takes over the task of controlling the room light. When a person enters the room, the lights are switched on automatically while it is switched off as the last person leaves. A Passive Infrared sensor is placed near the door and used to detect the presence of human beings. The output from this sensor is sent to the PIC16F84 microcontroller, which then controls the room lights via a relay. A pilot test carried out suggested a saving in the energy comsumptio

Automatic Control System Switching Roadway Lighting

Lack of attention to the information officer street lights, cause is not exactly the timewhen the blame lights street lighting street - the street in this city protocol. And whenit was already dark, the lights had not lit, so it can harm the users of the road. Werecommend that when it got bright lights - the lights switched off late, so muchelectricity is wasted with nothing - nothing.Given the problems above, the automatic switching is required that can control all thelights - the existing lighting on the road - the road protocol. In this case, the authoruses a light sensor (LDR) as an automatic controller roadway lighting that uses lightintensity to give a signal - a signal to other control components

Automatic Control with Experiments

Everybody has been a part of a control system at some time. Some examples of this are when driving a car, balancing a broomstick on a hand, walking or standing up without falling, taking a glass to drink water, and so on. These control systems, however,arenotautomaticcontrolsystems,asapersonisrequiredtoperformarole in it. To explain this idea, in this section some more technical examples of control systems are described in which a person performs a rol

Simulation Design of Automatic Control Room Lights

To be an efficient use of electricity doperlukan a tool that can control and regulate theuse of electric current by way of determining when power consumption is requiredand when the timing is not needed is to add a timer or a timer on the apparatus.For this purpose appropriate media to be utilized is to use the computer as a tool inthe media deemed appropriate and simplify the operation of the simulation controlroom lighting that will be discussed.To apply in accordance with the desired computer, software or software here alsoplay an important role. High-level programming language with ease inimplementation problems. Programming language to be used is Borland Delphi 3.0programming language similar to Pascal.The software will be created is expected to control and regulate or pewaktuyangTimer can be set manually on the computer and then apply it to the interface andcircuit simulation equipment room has been created

Error-Correcting Codes for Automatic Control

Systems with automatic feedback control may consist of several remote devices, connected only by unreliable communication channels. It is necessary in these conditions to have a method for accurate, real-time state estimation in the presence of channel noise. This problem is addressed, for the case of polynomial-growth-rate state spaces, through a new type of error-correcting code that is online and computationally efficient. This solution establishes a constructive analog, for some applications in estimation and control, of the Shannon coding theorem

Automation of the Continuous Coagulation Monitor

The development of automation in the past 50 years has paralleled the accelerating growth of today’s vast technological society. Automatic control systems are indispensable extensions of man\u27s brain that enable him to monitor and regulate his complex environment. The principles of automatic control have a wide range of applications and interests in virtually every scientific field. The need for automatic control systems in vital applications of environmental engineering is both real and urgent. Extensive pollution has resulted in unavoidable water re-use and in the inevitable establishment of stringent effluent standards. Both water and wastewater treatment processes have necessarily become more advanced and complicated. Automation can reliably provide the critical, sophisticated control required to maintain adequate treatment. In his pollution abatement or water quality program, the environmental engineer can employ automatic control systems to continuously and accurately monitor contaminant levels or the removal efficiencies of treatment processes and to effect rapid responses when treatment adjustment becomes necessary by automatically adjusting processes

Acr (Automatic Control Robot) Berbasis Atmega 8535 Sebagai Aplikasi Model Robot Menggunakan Rel

Arif Setiawan, Subali, in this paper explain that a fixed rail track used as a railway line. Application of rail as a direct path not only to train. However, there are also robots that use rail movement path. Rail crossings are used as the robot is not made of steel, but a line. This robot uses a single rail line is black with a white stripe background of a width adapted to the sensor mounted on the robot. Photodiode sensor lines will be detected, and then transmitted to the microcontroller 8535 as the brain or the source of the instruction that has been programmed. 8535 will detect the sensor output and then process the data received to proceed to the Driver that is connected to the DC motor. The output of the microcontroller 8535 will also be displayed through the LCD as the display position of the sensor and input characters. As an added speed control robot 4x1 keypad which will give instruction in the form of characters into the Microcontroller
