Monitoring electrical characteristics using electronics seems like it should be the easiest to work with, after all, microcontroller inputs are just voltage sensors. However, once you step outside of their common operating voltages, more is required. We stock a variety of easy to use voltage and current sensors, as well as panel mount gauges that combine sensing and displaying into one convenient module.
