What a sensor basically does is, it takes the physical change or mesures the physical change and convert that change into some voltage, that voltage undergoes some changes like may be it can be amplified or may be not, <br>
After that there is some mathematical relation, the voltage values are raw it's not a data its fed into some function whose output is the valuable data that we the user actually want from the sensor.
<br>
<strong>How it's performed</strong>
<br>
There are various libraries for various sensors, the libraries are nothing but some line of codes which include some fucntions, from which we call those predefined functions to make our main code easy and simple. The library files mostly includes all the conversion formula from which we get the output data from the sensor.

As its name implies, Digital Sensors produce a discrete digital output signals or voltages that are a digital representation of the quantity being measured. Digital sensors produce a Binary output signal in the form of a logic “1” or a logic “0”, (“ON” or “OFF”). This means then that a digital signal only produces discrete (non-continuous) values which may be outputted as a single “bit”, (serial transmission) or by combining the bits to produce a single “byte” output (parallel transmission).

<h3>HCSR04- Ultrasonic sensor</h3>
The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. It comes complete with ultrasonic transmitter and receiver modules
