Check Sensor status

Hello!

Here is my question.

Is there any way to check if sensors are ready to be read or not?

For example, I put a temperature sensor on Arduino analog pin 5.

Somehow the sensor is unplugged. In this case, can Arduino detect this situation?

If I put other digital and analog sensors, is there any common way for this purpose?

Thanks

BR

Depends on the sensor and its interface and optional its library ...

Tell us more what sensors do you have in mind?

Sure, put a pullup resistor to 5V on the input pin - if it becomes unplugged it will read back as 1023 all the time. Or High if its a digital pin.

Thanks! I have not decided what types of sensors and interfaces I use. I was wondering how we solve these problems as general.

Thanks for your information. I was wondering about the value(1023) when I received it last time. I think it is a good way to handle my question.
