DEVELOPMENT OF A NEW GENERATION OF MAGNETIC CONTACT BASED ON HALL-EFFECT SENSOR

Abstract

This paper describes the development of a new generation of magnetic contact. The development of this new generation of the magnetic contact is a part of the research activity of the security engineering laboratory. The new generation of magnetic contact is based on the Hall-Effect Sensor and microcontroller unit. Older magnetic contacts use a simple reed relay with only two states – normally closed or normally opened. The combination of the Hall-Effect Sensor and microcontroller unit provides advanced possibilities such as a programmable level of magnetic field sensitivity, adding different communication modules, programmable inputs/outputs etc. The results of this paper explain proposal of the new generation of magnetic contact, which can be used not only as a part of intruder alarm systems but also as a part of smart homes and other autonomous systems. The content of the paper can be used for even deeper research and by security systems developers as well.
