Hello Anybody used the smartec smths10 for humidity measurement? I'm having problem calibrating the sensor on a circuit that i have built. The circuit is built off the schematics in the smths10 datasheet. The problem is that the output varies between GND and Vcc thou it should be between GND and 0.5*Vcc, and it doesn=B4t seem to be linear neither. What could I have done wrong. Maybe the sensor is damaged?! The circuit is quite simple so I don't think I've miss wired it. Any help, comments is appreciated.
