Physical quantity, particularly humidity detection device, and related detecting method |
| abstract |
A pair of identical humidity sensors (S 1 ) and (S 2 ) are in the same environment, so that they identically react to humidity effects; a sensing circuit includes an operational amplifier ( 10 ), its input ( 15 ) receiving from the first sensor (Si) a signal changing with humidity according to a logarithmic law, while the second sensor (S 2 ), inserted in the amplifier feedback, reacts to humidity changes in the same way as the first sensor (Si) and consistently modifies the gain. The output signal (V 0 ) is compensated, and has a substantially linear progression with humidity. |
