Description :

The IR868LR family is an infrared passive sensor for indoor application. All objects with a temperature above absolute zero emit heat in the form of radiation. Usually this radiation is not visible to the human eye it radiates at infrared wavelengths, but electronic devices designed for such a purpose can detect it.

The term passive in this instance refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. They work entirely by detecting the energy given off by other objects. PIR sensors don't detect or measure "heat"; instead they detect the infrared radiation emitted or reflected from an object. The PIR sensor integrates a dual element pyroelectric detector for the detection of body heat in order to activate the alarm in case of intrusion.

The sensor is suitable for apartments, offices, shops, buildings in general this thanks to the possibility to adjust its sensitivity, even for small areas such as motor homes. It has been designed to fit perfectly with any environment, aesthetically pleasing, compact and remarkably robust.

The use of digital technology obtained by the use of the microcontroller, coupled to the Fresnel optics it provides good accuracy in detecting (37 beams spread over 3 horizontal levels), immunity false alarms and high reliability without reducing the sensitivity of the IR868LR.

The device is protected against tampering of the container; in case of tampering it transmits the code that

identifies this type of event. It has a variable coverage from 8 to 20 meters adjustable with a trimmer with an aperture of 100° to adapt to installation requirements and it has a temperature compensation and a white light filter to minimize false

alarms.

Of considerable importance is the low power consumption in standby mode that allows obtaining a remarkable battery life, minimizing its replacement during operation. Furthermore, the joint allows to easily obtaining the right inclination in order to cover optimally the desired area.
