Kamoer ATO One SE is a smart water replenishing device for meeting the needs of using freshwater reservoir. As long as the sensors and refill pump are installed, it can work after powering on without any settings. A Kamoer standard 1 optical level sensor is used to monitor the water level to determine whether water needs to be replenished, whilst the Kamoer standard 1 float level sensor is used to prevent overflow.

An optional float level sensor is available to monitor the freshwater reservoir for water shortage.

The Kamoer ATO One SE is rich in status indicators. When the Anti-overflow Sensor or overtime, the refill pump is not inserted or the freshwater reservoir is short of water, the ATO One SE will have an indicator light and a buzzer alarm.
