Abstract

Basically, most practical smoke detector circuits consist of three basic elements, the sensor, control circuitry and alarm sounding device. This project adds an additional microcontroller at the sensors parts and at the control panel, a system that can cover more than one zone in the house, a remote control for arming and disarming functions and a pair of RF transmitter and receiver to make the entire system wireless. With Universal Asynchronous Receiver Transmitter (UART) function provided internally by the microcontroller, there is no need to use decoder and encoder pair to vary the signal. This function is enough to make both microcontrollers in transmitter and control panel to work in pair. This whole system was designed to be small and convenient so that it can be handled easily especially with additional remote control function.
