Binary encoding  is used to represent the PIR sensor
status information on the chromosome.

Each pyroelectric element of a PIR sensor
(there are at least two) receives a variation of infrared radiation when a heat source moves in the sensor's area of detection.
detect this radiation and put it into a system that takes an action based on a change of state in this radiation field.
Featuring 1280 x 720 HD resolution with a built-in passive infrared (PIR) sensor, iSensor HD Patio, is highlighted by its unique ability to detect motion movement with its PIR sensor
. Unlike conventional CCTVs, iSensor HD Patio's protector offers a special membrane to allow body heat to be detected by the PIR sensor
It can be programmed to act as a remote PIR sensor
or as a remote trigger for cameras.
For this purpose the PIR sensor
was selected as a base detector.
The Hyper PIR sensor
has a range of 60' and can be set to auto so its sensitivity automatically adjusts based on the ambient temperature.
They had to be kept in optimum condition considering the incredible rarity and value of the collection." The glowing effect is supplemented by LED backlighting integrated within the cabinet, which is activated via a PIR sensor
when a customer approaches the display.
A human, vehicle or a large animal emits their own heat source that the PIR sensor
can see and immediately triggers the motion activated construction camera to start taking pictures.
As shown in Figure 9, the suggested system senses user location, behavior, and power consumption by means of the three types of sensors (PIR sensor
, piezoelectric sensor, and power sensor) for context acquisition, and then the collected data is sent to the server through the gateway as information for context awareness.
