PIR sensor detects a human being moving around within approximately 10m from the sensor. Your email address will not be published. This allows it to sense when an animal passes in front. The relay and the buzzer get off automatically after a particular time duration set by the user. PIR: Priority Intelligence Requirement: Military and Defence: PIR: Passive Infra Red: Military and Defence: PIR: Pass In Review: Military and Defence: PIR: Problem Identification Report: Military and Defence: PIR: Priority Information Requirement: Military and Defence: PIR: Priority Intelligence Requirements: Military and Defence: PIR: Primary Image Record: Military and Defence: PIR PIR sensor is an electronic device that measures the infrared in its field of view. There are three IR regions on spectrum named as near-infrared (0.75-3um), mid-infrared (3-6um), and far infrared (higher than 6um). The term passive in this instance means that the PIR device does not emit an infrared beam but passively accepts incoming infrared radiation and “Infra” meaning below our ability to detect. The diode 1n4007 is used here to protect the relay from reverse current flow. One is smaller and looks simpler that costs about $1.28 on Aliexpress. ek field mai kafi kiya ja rha hai.
