PIR sensors are widely used to detect human motion, by responding to a change in the temperature pattern across the field of view of the sensor [11]. Modeling the analog response of passive infrared sensor. Model predicts sensor's analog response matching reasonably well with experiments. Copyright is held by the owner/author(s).

We have used two types of feature sets: a raw data set and a reduced feature set composed of amplitude and time to peaks; and passage duration extracted from each PIR sensor. 6.2.3). the ultra low power feature of PIR sensors becomes attrac-, disjoint but adjacent areas along with simple-to-mou, tic lenses (to improve the range of sensors), w, objects that consist of warm-blooded living b, robot tracking [10]) that uses binary output from the PIR, mation provided by amplitude, phase and frequency of the, analog signal from PIR sensors for detection, ranging of the, detect the presence of a human, but also his/her height, di-, If the person has a special gait or gesture associated with his, least differentiate people, which is not possible with binary, sensors are not well-studied, there is a gap in literature. In this paper, the problem of intrusion detection using passive infrared sensors (PIR) is investigated. The objective is to reduce the overall energy consumption of these sensors. [4]. $7.117. The trials were done with 20 different people. In particular, by alternating the effective polarization of the sensing elements in a PIR sensor, it is possible to determine the relative direction of the movement of an object moving on the motion plane of the PIR sensor. We have performed classification analysis with well-known machine learning algorithms, including instance-based learning and support vector machine. It employs a sensor array that endows the platform with a spatial-resolution capability. We also show their correspondence with the range, speed and size of the moving object. The signal is modeled by a sum of exponentially modulated sinusoids. With the combination of signals from different to, at pre-defined locations, it was possible to overcome the pa-, rameter dependency problem and arrive at an acceptable, or vertically opposite to each other with F, not overlapping (Fig.
