The advancement of smart sensor technology has allowed us to design and development of a flexible reliable smart gas detection system to detect gases such as combustible air contaminants in the environment. The system composed of three modules the base station, wireless sensor array, and an intelligent wireless alarm unit which offers high reliability, flexibility and uninterrupted sensing, these are achieved by incorporating various intelligent protocols like auto sensor calibration, sensor handover, wireless threshold fixation and intelligent alarm mechanism, the sensor node consists of three gas sensor, one temperature sensor and one pyro-electric infrared sensor (PIR) which enhance the sensing intelligence. Sensed data digitized and processed by peripheral interface controller (PIC) 16f877A based centralized embedded platform and wireless communication is achieved with a pair of 433 and 315 MHz amplitude shift keying (ASK) wireless module. The encoding and decoding of sensed data offer a high secure gas detection system.
