An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings. It does this by either emitting or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion..
Just so, what is the purpose of IR sensor?
An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the motion. These types of sensors measure only infrared radiation, rather than emitting it that is called a passive IR sensor.
Likewise, how do IR sensors detect obstacles? An infrared sensor emits and/or detects infrared radiation to sense its surroundings. The basic concept of an Infrared Sensor which is used as Obstacle detector is to transmit an infrared signal, this infrared signal bounces from the surface of an object and the signal is received at the infrared receiver.
Secondly, can IR sensor detect human?
The Passive Infrared (PIR) sensor is used to detect the presence of human. But this detects the human only if they are in motion. The Grid-EYE sensor detects the human using the infrared radiation radiated by the human body. Every human radiates the infrared energy of specific wavelength range.
What is active IR sensor?
Active infrared sensors are the types of infrared sensor that emit infrared radiation which is later received by the receiver. The IR is emitted by a IR Light Emitting Diode (LED) and received by photodiode, phototransistor or photoelectric cells.

IR-based proximity sensor can't work in dark environments. Such sensors can work in the dark or inside the enclosure. Since the IR-LED is built into the sensor module, there's no need for an external light source to measure the distance from the sensor to the object (Fig.Is IR sensor digital or analog?
The sensor provides a digital as well as analog output. An on board LED is used to indicate the presence of an object. An IR LED (transmitter) emits IR light, that light gets reflected by the object, the reflected light is received by an IR receiver (Photo Diode).Can IR sensor detect water?
