![]() There are two types of PIR sensors which include the following. Working temperature ranges from -20-+80☌.Operating modes are repeatable & Non- Repeatable.It can differentiate between the movement of an object & human.The recommended input voltage supply is +5V.The features and specifications of the PIR sensor include the following. Once a person leaves the detecting region, then the delay will turn off the switch automatically. If the person does not leave the detecting region, the sensor switch will be turned on continuously. So this type of sensor light devoid of any switch is generally known as PIR motion sensor light. Once the human body moves away from the detecting region, then IR waves are not obtained & the lights are turned off automatically. Whenever a person enters the detecting range, then the sensor light will get the IR wave automatically from the human body, the IR wave will be detected & the light will be turned ON. It is lightweight, slim & outstanding light gathering capacity which will make it very useful for making this sensor small in size and also powerful. The Fresnel lens in the sensor increases the sensor’s field & range of view of the sensor. ![]() These sensors are most frequently utilized in motion detectors, security alarms & automatic lighting-based applications. So PIR sensor is particularly designed for detecting such infrared radiation levels. So this kind of radiation is not observable to the human eye as it is emitted at IR wavelengths. So if the object is hotter then it emits more radiation. Generally, all objects at above zero temperatures produce heat energy in the IR radiation form. PIR sensors can detect the movement of an animal or human within a fixed range. In PIR sensor, the term PIR stands for “passive infrared sensor”. PIR sensor definition is a sensor that is used to measure infrared light radiating from objects like the human body or animals. So this article discusses an overview of a PIR sensor – working with applications. All these readily available resources, it has really helped beginners to learn about the passive infrared sensor. Since these sensors are designed with many benefits they have been used in different electronic projects related to Raspberry Pi & Arduino. These sensors are less costly, very simple to utilize, and consistent, so applicable in door openings, security alarms, vending machines, automatic lighting switches, lift lobbies, and many more. PIR sensors are everywhere because it is almost impossible to visualize without them every day in modern life.
