The performance of the sensors of a low cost Short Message System (SMS) based home security system equipped with motion sensor, smoke detector, temperature sensor, humidity sensor and light sensors has been studied. The sensors are controlled by a microprocessor PIC 18F4520 through the SMS having password. The operation of the home security has been tested on Vodafone-Fiji network for emergency and feedback responses for 25 samples. The GSM experiment showed that it takes about 8-10s for the security system to respond the occupant and relevant civil authorities in case of emergency.
