Microcontroller based Environment Monitoring and Load Control System

Abstract

Automation can be described as a process following pre-determined sequential steps with a little or without any human exertion. Automation is provided with the use of various sensors suitable to observe the production processes, actuators and different techniques and devices. In this project, the automation system developed is an automatic lamp and an automatic fan on the smart auditorium. Both of these systems will be processed using microcontroller. A microcontroller is used to obtain values of physical conditions through sensors connected to it. In the automatic lamp system required sensors to detect the light of the LDR (Light Dependent Resistor) sensor. While the automatic fan system required sensors to detect the temperature. The lamp can turn on automatically when the light begins to darken, and the lamp can also turn off automatically when the light begins to bright again. Then for the fan, it can also turn on automatically when the temperature is greater than 28°C, and the fan speed can also be adjusted. The fan may also turn off automatically when the temperature is less than equal to 28°C it also can automatically visitor counter shown in the LCD display controlling by the sensor
