What is the difference between Proteus AQUO and Proteus L5 Level Sensor?

Proteus AQUO has a sensor cable with metallic electrodes at the end of the cable. When water touches these two electrodes at the same time, the alarm is triggered. AQUO can detect as low as 1/16" of water

Proteus L5 sump pump level sensor uses a float switch detector. The moving float switch rises/ falls as water level rises and this mechanical action triggers the alarm. As there are no exposed electrodes, the chances of condensation in high humidity spots such as sump pits are minimized, thereby avoiding false alerts.

Power supply

All proteus sensors, unless specified otherwise, are powered directly from a 120-240V AC wall outlet. Simply plugin the sensor to a standard wall outlet and you are good to go.
