Many analogue sensors are just variable resistors that are triggered by different tangible feedbacks.
By taking a reading of the resistance we get an idea of what the sensor is sensing. This could be temperature, light, pressure, or a number of other things.
Here is a simple set up showing a photo resistor at work.
