Kamoer ATO One RO - Smart Auto Top Off System

Reliable Auto Top Off with Solenoid Valve Control

The Kamoer ATO One 2 RO is an intelligent auto top-off system designed for aquarium setups using reverse osmosis (RO) water. This upgraded version features a solenoid valve for precise water control and easy operation.

Key Features

• Plug & play operation — install the sensors and solenoid valve, power on, no setup required

• Magnetic sensor mounting for easy installation and adjustment

• Dual optical level sensors:

  • Blue sensor monitors water level for top-off activation

  • Red sensor prevents overflow protection

• Visual and audible alerts for overflow, refill overtime, or low water in the reservoir

• Rich status indication via indicator lights and buzzer alarms

Ideal for both freshwater and marine aquariums using an RO top-off system.

How It Works

Once powered on, the system automatically detects water levels via the optical sensors. The blue sensor initiates a top-off when the water level drops, while the red sensor halts the process to prevent overflow. The solenoid valve ensures secure, leak-free water control.

If the refill takes too long, overflows, or if the reservoir runs low, the system provides both light and sound alerts for safety.
