heater of SHT85 Sensirion

Hello
I'm using the SHT.Sensor library to control the sensirion's SHT85 sensor, but I see that in this library there isn't command for switching on and off the internal heating
Can anybody tell me if its possible modify SHT.Sensor library to allow the command to manage the internal heating ?

I'm missing the link to the library you're using.

I used this library as a work base

I don't know if there is a complete SHT85 sensor library, as I couldn't find it

The library doesn't support the SHT85 explicitly, it only supports the functionality of the SHT3x chips which is a subset of the SHT85 functionality.

You can add your own method for heater control. The command bytes are 0x30, 0x6D for heater on and 0x30, 0x66 for heater off. So the code may look like

bool setHeater(bool state) {
  Wire.beginTransmission(0x44);
  Wire.write(0x30);
  Wire.write(state ? 0x6D : 0x66);
  if (Wire.endTransmission()) {
    return false;
  }
  return true;
}

You know that you usually don't need the heater, don't you?

For the basic functionality you can use any SHT3x library.
