In the example above, Tc = 23.81 degrees C, V_ad which is the output of the HIH-4000 sensor is 3.17 VDC and the supply voltage V_dd is 5.03 VDC. The relative humidity may then be calculated as; Note that the RH #166 Sender Unit is powered (+5 VDC and GRD) by the master unit; TM #128, IOM #135E, IOM #136 or IOM #142A.
A germanium diode is a diode made using the element Germanium in stead of Silicon (Silicium). While both perform the same function (they only let current pass through them in one direction) there are some differences between the silicon and german...
A tunnel diode is a two-terminal device with an n-type semiconductor acting as cathode and a p-type semiconductor acting as anode. It is heavily doped, which in turn creates a narrow depletion zone like a Zener diode. The current-voltage characteristic of a tunnel diode has a strong non-linear nature, as well as a negative differential resistance region. Two distinct advantages of tunnel diodes are longevity and very high speed.
