Using SD Card Module for 2 sensors

Hello everyone,

I’m using an Arduino UNO, two MCP_9808 temp sensors and a SD Card Module. My SD card is formated and already in FAT32.
My goal is to create a .txt file where i can note every minute the temperature of each sensor.

Here is my code :

 #include <Wire.h>
#include "Adafruit_MCP9808.h"

// Create the MCP9808 temperature sensor object
Adafruit_MCP9808 tempsensor_1 = Adafruit_MCP9808();
Adafruit_MCP9808 tempsensor_3 = Adafruit_MCP9808();

void setup() {
  Serial.begin(9600);
  Serial.println("MCP9808 demo");
  Wire.begin();
 
  
   
  if (!tempsensor_1.begin(0x18)) {
    Serial.println("Couldn't find MCP9808 #1!");
   while (1);
    }
 
 if (!tempsensor_3.begin(0x1C)) {
Serial.println("Couldn't find MCP9808 #3!");
   while (1);
  }
}

void loop() {

  float c1 = tempsensor_1.readTempC();
  
  float c3 = tempsensor_3.readTempC();
  Serial.print(c1); Serial.print(';');
 Serial.print(c3) ; Serial.println(';') ;
 delay(4000);

}

The code works : I have both temperature in the delay i want (i will fix it at 60sec later) but i made several tests and i don’t know how to code in order to write every minute, in my SD Card those temperature.

Is there a simple code to include in mine please?
Thank you
