Print the amount of vibration on the screen in C

Question

I am able to detect a vibration when I am using 801s vibration sensor module sensor

How to measure and print the amount of vibration level on the screen in C? I am checking now only state: HIGH and LOW. I am using a digital signal not analog signal so my question is, can I use this type of signal in this sensor to display the value of vibration or we can't. How to retrieve the data from this sensor in C, value not only states high or low.

I am playing with the code from this video project

#include <wiringPi.h>
#include <stdio.h>
#define VibratePin 0
#define Gpin 1
#define Rpin 2
int tmp = 0;
void LED(int color)
{
pinMode(Gpin, OUTPUT);
pinMode(Rpin, OUTPUT);
if (color == 0)
{
digitalWrite(Rpin, HIGH);
digitalWrite(Gpin, LOW);
}
else if (color == 1)
{
digitalWrite(Rpin, LOW);
digitalWrite(Gpin, HIGH);
}
else
printf("LED Error");
}
void Print(int x){
if (x != tmp){
if (x == 0)
printf("Vibration Detected:  .......Device1 On\n");
if (x == 1)
printf("Vibration Detected:  Device2 On........\n");
tmp = x;
}
}
int main(void)
{
int status = 0;
int tmp = 0;
int value = 1;
if(wiringPiSetup() == -1){ //when initialize wiring failed,print messageto screen
printf("setup wiringPi failed !");
return 1;
}
pinMode(VibratePin, INPUT);

while(1){
value = digitalRead(VibratePin);

while(1){
value = digitalRead(VibratePin);
if (tmp != value){
status ++;
if (status > 1){
status = 0;
}
LED(status);
Print(status);
delay(1);
}
}
return 0;
}

The Raspberry Pi does not have any analog input PINs. Thus you will not be able to interpret analog input signals without some additional hardware.

In order to be able to read not only HIGH or LOW levels from your sensor, you need to use an analog-to-digital converter (ADC), e.g. in the form of a ADC-HAT extension for the Rasperry Pi. Then you can connect the analog output pin of your sensor A0 to the ADC and read in the analog input level.
