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.

future scope for human detection robot using pir sensor

Human detection robot is not a new technology. Many types of human detection robots were designed depending on the application. During the natural calamities like earthquakes, it is difficult to rescue the human beings under the buildings. Though detection by rescue team is done, it consumes a lot of time. Detection of human in appropriate time is very important in such situations. This article presents a simple human detection robot that is operated manually using RF technology.

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

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

automatic door opening system using pir sensor

The system puts forward an automatic and precise door opening system based on human movement sensing near the door. Well opening a door in places like hotels, Shopping complexes, and offices can be a tedious task and sometimes requires hiring a person just for the sake of opening door whenever a person arrives.Well this project proposes a system that allows for automatic door opening solution by sensing human presence near it. Our system achieves this functionality with the help of PIR sensors. PI ....etc

human detector using pir sensor seminar ppt

Pyroelectric infrared (PIR) sensors are widely used as a presence trigger, but the analog output of PIR sensors depends on several other aspects, including the distance of the body from the PIR sensor, the direction and speed of movement, the body shape and gait. In this paper, we present an empirical study of human movement detection and idengification using a set of PIR sensors. We have developed a data collection module having two pairs of PIR sensors orthogonally aligned and modified Fresnel lens ....etc
