This project is used for home security system using laser , fire sensor. In this project we are using LDR sensor to sense light falling on it’s surface. When there is any movement , laser beam gets inturrupted and logic signal is then given to microcontroller. The micrcontroller takes proper action to turn on alarm system through transistor driver circuit. The controller used in this project is ATMEGA328. The 16*2 LCD Display is also interfaced with the microcontroller in order to show the proper status of the sensor interruption. SMS alert is sent to user phone. We are also using temperature sensor to sense fire. If it crosses threshold value mentioned in program, alert SMS is sent to user phone
