What is the purpose of a distance sensor?
As its name suggests, to easily define distance sensors, it is sensors used for determining the proximity of an object without any physical contact involved. How does distance sensor work?
What is the working principle of a proximity sensor?
Proximity Sensor Working Principle. The inductive proximity sensor circuit is used for detecting the metal objects and the circuit doesn’t detect any objects other than metals. The above proximity sensor circuit diagram represents the field produced by the coil, which is generated by providing a power supply.
How big of a gap does a proximity sensor need?
As a rule of thumb, an inch gap between the IR-emitter/detector pair makes it possible for the proximity circuit to discover a target approximately half to 1-inch apart. Lighter shaded targets reflect much better and can perform at increased distances than those created from deeper elements.
How does an IR distance sensor work in a PSD?
IR distance sensors work through the principle of triangulation; measuring distance based on the angle of the reflected beam. Here’s an illustration of how IR distance sensors work through triangulation: The sensor in the PSD will then determine the position/distance of the reflective object
What is the operating range of a proximity sensor?
These inductive proximity sensors are available in AC, DC, and AC/DC modes (universal modes). The operating range of the proximity sensor circuits is from 10V to 320V DC and 20V to 265V AC.

Why is op amp used in proximity sensor circuit?
Op-amp (IC LM358): Op-amp or operational amplifier is a multi-purpose ic and is highly revered in the electronics world. In this project op-amp is used as a comparator. LM358 IC has two op-amps which means we can make two proximity detectors using just one IC. The reason to use op-amp in the circuit is to convert analog signal into digital signal.
