How to make i2c Custom Sensor without Adafruit Library?

ESPHome
1

Hello I realy love use ESPHOME.

I have some other question to make i2c custom components.

I have no idea about coding, but esphome make it easy enough to challenge make something

I have i2c device which has a fuction to sensing Radon,

I can make Test Custom Sensor but Adafruit Library only

It has no Adafruit library, so I don’t know How to Integrate.

so I have no idea, How to Integrate my ESPHOME ?

void setup() {  //Arduino Initialize  
  Serial.begin(9600);  
  Wire.begin();  
  Serial.println("Gamma Sensor Sensing Start"); 

 //Read Firmware Version  
  Gamma_Mod_Read(0xB4);  //Reset before operating the sensor  
  Gamma_Mod_Read(0xA0);  
  Serial.println("================================================"); }

void loop() {
  delay(1000);  
  Gamma_Mod_Read(0xB0); // Read Status  
  Gamma_Mod_Read(0xB1); // Read Measuring Time  
  Gamma_Mod_Read(0xB2); // Read Measuring Value (10min avg.)  
  Gamma_Mod_Read(0xB3); // Read Measuring Value (1min avg.)  
  Serial.println("================================================");  
  sec++; }

void Gamma_Mod_Read(int cmd){  
   /* Begin Write Sequence */  
  Wire.beginTransmission(addr);  
  Wire.write(cmd);  
  Wire.endTransmission();  
   /* End Write Sequence */  
  delay(10);  
   /* Begin Read Sequence */  
  Wire.requestFrom(addr, 2);  
  byte i = 0;  
  while(Wire.available())  
  {    
  buffer[i] = Wire.read();    
  i++;  
  }  
  /* End Read Sequence */   
  
   /* View Results */  
  Print_Result(cmd); 
}

If someone can make i2c custom ESPHOME sentence without adafruit Library
please let me know How to setup ESP Yaml and Custom.h file

Thanks to Everyone for your Knowledge and Experience.
