automatic room light and fan controller doc

ABSTRACT

This paper reports on a system that can save electricity. Many times we leave the room and hall without switching off lights and fans, thus electricity is wasted. In this work we have presented a system in which energy will be saved based on number of people entering in or leaving out of the room.
If there is no person in the room, then light and fan will be switched OFF. On the other hand as soon as any person enters the room, light and fan will be switched ON. On the basis of the intensit ....etc

ABSTRACT

Ceiling fan operation control for tuning the fan on and off based on a passive infrared sensor, combined with a temperature sensor to regulate the speed of the fan. The passive infrared sensor, the temperature sensor and controls for both are in a housing directly mounted to the fan motor of the ceiling fan. The controls can be set screws covered by a removable cap. The passive infrared sensor can include a fresnal lens for sensing a 360 degree circumference beneath the fan, and a photo-optical sensor such as a photocell, which suspen ....etc

Arduino-Based Automatic Temperature Fan Speed Controller
In many small or large industry, you may have seen such a lot of fan that speed is control according to the temperature of the place. Thus, during this article, we have presented a demo of that application. It's assumed that you have an idea of how to read reading from the temperature sensor IC. In industry
temperature range will be more than 100 oC but here we will work on the very low range.

embedded temperature based fan speed controller using 89c51 microcontroller

Abstract

Temperature controller can be done by using Electronic circuit, Microprocessor or microcontroller. Now microcontroller is advanced among all above circuits therefore we are using Microcontroller for temperature controlling.In this project, microcontroller 89s51 forms the processing part, which firstly receives data from ADC. ADC receives data from temperature sensor through amplifier. Then microcontroller 89s51 performs the comparison of current temperature a ....etc

Abstract

The project is based on the working of temperature controller using LM35 and fan ascooler. The circuit automatically senses the temperature and works normally within a particulartemperature range. Above that range the sensor produces a signal and automatically turns on thecooling fan to control the testing temperature. 0-100 C electronic temperature controlled relay isa circuit using which the temperature can be controlled with the help of a LM35 temperaturesensor.The LM35 series are precision integrated-circuit temperature sensors ....etc
