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...
Vacuum Diode History Working Principle and Types of Vacuum Diode. History of Vacuum Diode. In November 16, 1904 first vacuum diode was invented by Sir John Ambrose Fleming and it is also called the Fleming valve, the first thermionic valve. In those days there was no existence of p-n junction in electronics field. A conceptual figure of vacuum diode is shown below. How does vacuum tube diode work? Here the vacuum diode works mostly like modern diode. But its size is larger. It consists of a vacuum container with cathode and anode inside. This cathode and anode are connected across a voltage source. The anode is applied with positive voltage with respect to cathode.
