All Proteus WiFi Sensors require a 2.4 GHz Wi-Fi network for operation.

When connecting more than one sensors

Proteus can support multiple level sensors. They all connect to a single base unit through a splitter included with the package.

NOTE: When connecting more than one level sensors to the base unit, the base unit will not be able to distinguish which of the multiple sensors detected water. If you need to identify specifically which sensor triggered, then you will need individual base units which can be named to match your installed locations. The alerts will include this sensor name so you can identify each sensor.

Voice Call Alerts

Voice call alerts are part of the advanced options package and is a paid option. Notifications are charged on a per call basis at 9¢/ call

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.
