Fire Alarm System using AVR Microcontroller

In this project, we are going to make a Fire Alert System using ATMEGA8 microcontroller and fire sensor. Fire sensor can be of any type, however we are using IR (Infrared) based Fire Sensor. Although IR based Fire Sensors have some disadvantages mostly of inaccuracy, it is the cheapest and easiest way to detect fire. [caption id="attachment_34834" align="aligncenter" width="650"] Fire Alarm System using AVR ...

Automatic Railway Gate Controller with High Speed Alerting System

The main aim of this project is to operate and control the unmanned railway gate in the proper manner in order to avoid the accidents in the unmanned railway crossing. In a country like ours where there are many unmanned railway crossings, accidents are increasing day by day. These train accidents are due to the absence of human power in the railway. In order to overcome the accidents due to the above probl ...

Sleeping Security – Smart Keypad Lock using AtMega16

This project is just a smart version of any keypad lock. What’s smart about it is that it can detect whether it is needed by the user or not and accordingly switches itself to take a sleep. Making a microcontroller to sleep reduces power consumption as well as increases its usage span. Many of you must be wondering that would it be secure enough to make a lock go to sleep, isn’t it. Don’t worry, when a micr ...
