CJMCU 6701 gsr sensor

[Jivansha]

I am trying to read GSR values from Generic CJMCU 6701 Arduino compatible sensor and Arduino UNO.
Following are the connections I have tried -
Sensor -> Arduino
+5V ->+5V
GND->GND
OUT -> A0
CS-> D10
MIS->D12
SCK-> D13

I wrote the following code to read the values -

#include <SPI.h>

int sensor_in =A0;
int raw=0;
int Vin=5;
float Vout=0;
float gsr=0;

void setup() {
  
  pinMode(12, INPUT); //MISO
  pinMode(13, OUTPUT); //CLOCK PIN
  digitalWrite(10, HIGH);  // ensure Slave select stays high
  Serial.begin(9600);
  SPI.begin();
}

void loop() {
  
  // enable Slave Select
  digitalWrite(10, LOW); // enable communication with slave
  delay(500);
  
  raw= SPI.transfer(0x00);// read from sensor
  Serial.println(raw); // display reading on serial monitor
 
  // disable Slave
  digitalWrite(10, HIGH);  
  Vout = (Vin * raw) / 1023;    // Convert Vout to volts
  gsr = 100*(1 / ((Vin / Vout) - 1));
  Serial.println(gsr);
  delay(1000);
}

The only values being displayed is 0. Please help me to rectify it and/or share any related resources that might be useful.

I have the same problem reading this sensor. Did you solve the problem. I tried to use Mcp320x library, but it does not work

This code very nice:
const int GSR=A0; //
int sensorValue=0; //
int gsr_average=0; //

void setup(){
Serial.begin(9600);
}
void loop(){
long sum=0;
for(int i=0;i<10;i++)
{
sensorValue=analogRead(GSR);
sum += sensorValue;
delay(5); }
gsr_average = sum/10;
Serial.println(gsr_average);
}
