Abstract
A device for sensing a level of a fluid, the device including a microcontroller and a probe coupled to the microcontroller. The microcontroller applies a given DC potential to the probe for a first period of time, measures a voltage associated with the level of the fluid to be sensed after the first period of time, and applies a reference DC potential to the probe for a second period of time.
