Overview
Detectors sense smoke, light, motion, and abnormal temperature, and accordingly notify safety management systems of fire or intrusion. In general, such systems use 8/16-bit microcontrollers as a core and signals from sensors as control triggers. This basic operation is the same for almost every type of detector. In the security system that manages all the sensors, sensors are interconnected via a serial or wireless communication bus.
Renesas' range of low power 8/16-bit microcontrollers capable of highly precise analog detection is ideally suited for these applications. We also recommend our low voltage operation power supply ICs.
