I would like to initially take three different types of measurements and prototype the transducer, sensor, conversion from signal output to a computer-friendly signal, and a rough software service to monitor these signals.

The previous post touched on one these properties, namely temperature. The other two properties I would like to address are electrical current and several computer measures such as free memory and disk space. I realize the computer measurements are not common to the others, but I feel I need to test those types of properties as well.

I’d like to examine some possible sensor types for current. The main priorities are price, simple circuitry for a reasonable output signal, and sensitivity.

Next I will be looking into various ways to measure alternating current (AC) in the house.
