Submersion detection circuit and submersion detection apparatus using the same |
摘要 |
A submersion detection circuit includes a power source unit, a reference resistor connected between the power source unit and a voltage measurement node, a submersion unit configured to include a plurality of submersion measurement resistors connected in parallel to the voltage measurement node. Submersion contact terminals are formed at respective ends of the submersion measurement resistors, and a voltage measurement unit connected to the voltage measurement node and configured to measure voltage divided by the reference resistor and the submersion unit when the submersion contact terminals submerge. |
