RF Based Human Detection And Monitoring

Abstract

This project is developed for the users to find out the presence of Human using PIR sensor. It mainly consists of a PIR sensor. It senses the presence of Human. The output of the sensor is connected with a microcontroller unit. A LCD display is connected with the microcontroller through LCD driver. In the presence of human, the sensor senses the signal and sends signal to the microcontroller. The microcontroller analyses the signal and sends signal to the LCD display through LCD driver. The LCD display displays the presence of human. This can be implemented very easily to find the distance of the human to the particular place. Since microcontroller is used, the operations are very accurate. This uses microcontroller as PIC 16F73. The microcontroller programming is written in assembly language.
