Abstract
Measuring apparatus includes a first element having its impedance dependant on the state of its surroundings and a second element having a variable impedance connected to the first element. A voltage at the connection point between the first and second elements is converted into a digital value and the impedance of the second element is set based on the converted digital value. The surrounding state (e.g., humidity) is determined based on the converted digital value.
