| An infrared (IR) proximity sensor detects objects and measures distance without physical contact. IR sensor consists of an infrared emitter, a receiving sensor or array of sensors and a signal processing logic. The output of a sensor differs depending on the type – simple proximity detection sensor outputs //HIGH// or //LOW// level when an object is in its sensing range, but sensors which can measure distance output an analogue signal or use some communication protocol, like I2C to send sensor measuring results. | An infrared (IR) proximity sensor detects objects and measures distance without physical contact.
