Wireless alarm system in building for deaf disabled

Abstract

This paper presents a concept of design and development of abnormal event alarm for deaf disabled in a building. When the abnormal event has been occurred then the system will send alarm signal to transceiver number 1 that be used as repeater and/or alarm center. At alarm center, the alarm signal will be sent to transceiver number 2 that have vibration device inside. For experiment, the deaf disabled can recognize the abnormal events that are simulated in real world. However, missing detection can be occurred from high sensitivity setting for the sensor modules that affects to accuracy.
