INFRARED SENSOR
INFRARED ( IR ) SENSOR Infrared Light that is invisible to the human eye, INFRARED SENSOR detect the infrared frequency(Light) , and make the work done. In daily life we use many IR INSTRUMENTS ALARM SYSTEM CAMERA WITH IR SENSOR DAFINATION :- 1. An infrared sensor is an electronic instrument which is used to sense certain characteristics of its surroundings by either emitting and/or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion. Infrared Radiation. 2. An infrared sensor is a device that emits and/or receives infrared waves in the form of heat. While most infrared sensors transmit and receive infrared waves, some can only receive them. These types of infrared sensors are known as Passive Infrared Sensors (PIR sensors) or motion detectors. HOW IS WORKS : - Sensors are used to measure physical quantities such as temperature, light, pres...
