If a person or a warm-blooded animal enters the range of the PIR detector, the thermal radiation and movement are detected by the sensor and the alarm signal is sent via radio to the central unit. The sensor characteristic is adjustable to suit the room.
Radio water sensor warns immediately during an eventual water outlet and thereby, responsible to prevent damage by water. It reports humidity and water from 1.5mm upwards. It has two separately controlled measuring length and can differentiate such between emerging of humidity or water level from 1.5 mm upwards. Through a smart energy management, battery life-span of several years is achieved.
