In the non‐linear faint signal measurement, multiplications of amplifier are often needed to be
adjusted according to the signal intensity extent and the non‐linear region continually, however the measurement circuit is complicated, of low precision, and difficult to adjust. Using PGA, the
amplifier is designed to realize high‐accuracy, high multiplications; this amplifier and the singlechip circuit constitute the humidity detecting system of adjusting gain voluntarily. This system has excellent noise immunity and strong overcoming non‐linear performance.
