About this document

Inexpensive Humidity Measurement Circuit by w-vital is a document available to read on EtoBox.

The document describes a low-cost circuit for measuring relative humidity using an inexpensive humidity sensor. The circuit uses novel approaches to generate a stabilized square wave, linearize the sensor response through a logarithmic amplifier, and compensate for nonlinearities at low humidity readings. The design achieves accurate humidity measurement with only a small number of inexpensive integrated circuits.
