DEVICE FOR DETECTING MOTION BY PASSIVE INFRARED SENSOR WITH A 360° COVERAGE IN HORIZONTAL PLANE AXES X-Z.

摘要

Described is a device for detecting motion by passive infrared sensors with a 360° coverage in the horizontal plane axes X-Z and detection under the sensor area. The invention includes the optimisation of PIR sensor elements arranged in an electronic board, which processes the three signals with three infrared lenses for the radial total coverage, simultaneously receiving and processing the signal of other lens with radial pattern for performing the coverage under the sensor. This artefact provides characteristics that increase the sensibility of reception due to the reduction of distances between the sensor elements and the amplifier unit.
