Advanced Fire Alarm Using RF Communication

[摘要] This project demonstrates the application of RF (Radio Frequency) Communication. The proficiency of fire alarm circuit can be improved by incorporating the RF module in a way such that the temperature sensor and buzzer for alarm can be placed from one another. This provides flexibility of installing various sensors at different locations in a building and thus fire at a place would make the buzzer to go on. As soon as the buzzer goes on, an SMS is received on the mobile by GSM module interfaced through ATmega 328.
