The code programmed for the ESP by using the Arduino IDE can be applied directly to the Arduino UNO?

Depending on what libraries and features are used in your source code you may be able to re-build exactly the same source code to run on either the Uno or the ESP(32 etc) by changing Tools / Board. If there is something incompatible with your code for the selected board you should get a build error.

Yes, thanks a lot, I've received some error alerts.

hi Y2,
Please post your full Arduino sketch, I will try it out on my setup.

The same error is reported here and a solution is offered but there's no feedback about whether the solution worked

All I use in my project are sensors and I don't think I need to define any output pins in setup.
I modified my code a little and now it compiles without problems.

int lightState = 0;
bool TemperatureBool = false;
bool HumidityBool = false;
bool illuminationBool = false;
bool illuminationState = false;

uint8_t TemperatureValueInteger = 0;
uint8_t TemperatureValueDecimal = 0;
uint8_t TemperatureValue = 0;

uint8_t HumidityValue = 0;
uint8_t illuminationValue = 0;

uint8_t TemperatureOutput[8] = {0xA5, 0x5A, 0x05, 0x82, 0x00, 0x10, 0x00, 0x00}; //A5 5A 06 83 00 0A 01 00 02
uint8_t HumidityOutput[8] = {0xA5, 0x5A, 0x05, 0x82, 0x00, 0x15, 0x00, 0x00}; //A5 5A 06 83 00 14 01 00 05
uint8_t illuminationOutput[8] = {0xA5, 0x5A, 0x05, 0x82, 0x00, 0x20, 0x00, 0x00}; //A5 5A 06 83 00 18 01 00 08

        TemperatureValue = DHT.temperature;

        HumidityValue = DHT.humidity;
        HumidityOutput[7] = HumidityValue;
        Serial.write(HumidityOutput, 8);
        break;
    case 0x13://Humidity back
        HumidityBool = false;
        break;
    case 0x18://illumination start
      illuminationBool = true;
      illuminationState = false;
        break;
    case 0x19://illumination stop

Thank you so much! I have corrected my mistake, maybe I added the incorrect library for the temperature sensor, I have added a correct library.
