Abstract
A moisture meter (1) has a capacitive sensing circuit (11-16) feeding into a digital control circuit having a microcontroller (17). Input buttons (20, 22, 23) allow a user to select a material being surveyed. They also allow the user to instruct the meter (1) 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 (18) to a moving coil meter (4). This provides an easy-to-read display in which trends as the meter (1) is moved across a surface are easy to track.
