Abstract
A moisture meter ( ) has a capacitive sensing circuit ( ) feeding into a digital control circuit having a microcontroller ( ). Input buttons ( ) allow a user to select a material being surveyed. They also allow the user to instruct the meter ( ) to hold a particular reading. This allows it to be more conveniently read. The output of the digital control circuit is fed via an ADC ( ) to a moving coil meter ( ). This provides an easy-to-read display in which trends as the meter ( ) is moved across a surface are easy to track.
