Air humidity sensor. KHS-003

Humidity sensor which can measure the water vapor of the air precisely.
Proofreading data is attached individually.


Power supply voltage DC5V.
The voltage (analog) proportional to humidity is outputted.

Data logger and the feedback control use in engine management.


 Waterproof moisture-permeable plastic sheet attached.(phi42mm)
Crcumference is a seal, a sensor can be stuck on a plane part.
