PIR Sensors are called “Passive” because they don’t create any infrared light but are only used to detect it.In the PIR Sensor, two pyroelectric sensors are placed behind the lens to detect the change in IR level.When the body moves in the range of the PIR Sensor, the change in the environmental infrared waves is sensed by the PIR.A passive infrared sensor or PIR is a motion detector that detects the changes in the infrared light radiating from the bodies.Let's discuss the basic introduction of the PIR sensor: Where To Buy? Therefore, don’t worry if you have no experience with the sensors in Proteus. Same as the previous version, this PIR has four pins and the details of each of them will be discussed in detail later. Moreover, the design is improved a little bit and we have omitted the website link from the sensor to make it look professional. PIR V3.0 is analog in nature, has an error-free structure and the Pinout structure is better organized. These libraries were loved by the users and this motivated us to work more on it. PIR Sensor V1.0 Library for Proteus adds a digital PIR Sensor in Proteus, while the PIR Sensor V2.0 Library adds an analog PIR Sensor to simulate. We have already shared V1.0 and V2.0 of the PIR Sensor Library. Today, I am sharing version 3.0 of the PIR sensor library for Proteus.
