Electronic moisture meter.

Measurement of electronic non-electric quantities is of interest to many people, but depends on available sensors. One of the interesting, but difficult to measure, non-electric quantities is air humidity.
The humidity sensor can be the basis of extremely interesting experiments, and taking into account specific features, it can also be used to build moisture meters and regulators.

Basic parameters:

• Working temperature range 0 ... + 50oC
• Measurement range:
• HS12P 20 ... 90% RH (without dripping)
• HS15P 20 ... 100% RH
• Impedance at 50% RH 25oC 30 ... 90k? (± 5% RH)
• Operating voltage AC 1Vsk max
• Operating frequency range 50Hz ... 1kHz
• Power consumption 0.3 mW
• The printed circuit board and documentation are included

  A version with a set of independent components is available
