*HYDROS Sense Port accessory for your HYDROS Control aquarium controller platform
* Precision optical sensor for monitoring waste level in your protein skimmer collection cup
* Connect to your HYDROS Control aquarium controller and download the HYDROS app for wireless control

Precision optical sensor specially engineered to connect to any HYDROS Sense Port. The HYDROS Skimmer Sensor is a HYDROS Sense Port accessory that provides an easy and accurate way to monitor skimmate (waste) level inside your protein skimmer collection cup. Built specifically to be placed inside the collection cup of a protein skimmer, the HYDROS Skimmer Sensor can be incorporated into your HYDROS Control aquarium controller platform to alert you and take preventive action when the skimmate level reaches your set level. Once properly integrated to your HYDROS Control aquarium controller platform, the HYDROS Skimmer Sensor is powered and controlled by your HYDROS Control aquarium controller. By downloading the FREE HYDROS app, you can control any HYDROS-connected device with your Internet-enabled computer, smartphone, or tablet!

The HYDROS Skimmer Sensor contains no moving parts that can fail. It’s extremely tiny, measuring a little over a half-inch thick with a circumference the size of a US penny. The optical eye is magnetically coupled with the magnet side measuring only 1/4" thick. It can be mounted inside any protein skimmer collection cup up to 1/4" thick. When connected to a HYDROS Sense Port, your HYDROS Skimmer Sensor is powered by your HYDROS Control aquarium controller and requires no additional cords or power bricks for operation.

HYDROS is engineered, assembled and supported at CoralVue headquarters in Slidell, Louisiana USA.

Please Note: The HYDROS Skimmer Sensor includes ONLY the sensor. Other HYDROS devices and accessories sold separately.

Please Note: The HYDROS app is required to use your Internet-connected smart mobile device as a controller. The HYDROS app is downloadable via the Google Play Store and iOS App Store.

HYDROS Skimmer Sensor Specifications

  • Size: 0.75" diameter x 0.55" thick Sensor, 0.25" thick Magnet Mount, 98" long Cord
  • Max Mounting Thickness: 1/4" thick max
  • No Moving Parts
  • Magnetic Attachment
  • Purpose-built to be placed inside the collection cup of a protein skimmer
  • Attaches to any protein skimmer collection cup: you don't need to purchase a new lid or modify your collection cup for it to work
  • The HYDROS Skimmer Sensor uses a GX12 aviation-style connector, so your HYDROS Control aquarium controller maintains its IP65-rating (dust-tight and protected from water spray at any angle)
  • Powered, monitored, and controlled by plugging into a Sense Port on your HYDROS Control aquarium controller. No additional power cord is required.
  • Manufactured by AutoAqua, an official HYDROS Technology Partner.

HYDROS Skimmer Sensor Application Example
Connect your HYDROS Skimmer Sensor into a HYDROS Sense Port. Place the HYDROS Skimmer Sensor inside any protein skimmer collection cup up to 1/4" thick. Secure the optical sensor at the desired level using the magnetic coupling that sits on the outside of the skimmer cup. Once properly configured, the HYDROS Skimmer Sensor can be set to "tell" your HYDROS Control aquarium controller to turn the protein skimmer OFF to prevent overflowing when the waste (skimmate) level in the collection cup rises to the point it makes contact with the optical sensor. Keep in mind that your protein skimmer must be plugged into a HYDROS power source, like the HYDROS 4 Outlet WiFi AC Power Strip or HYDROS Smart WiFi Plug, for this sort of skimmer security to operate.

AutoAqua General Information
The HYDROS Skimmer Sensor is an Official HYDROS Accessory manufactured by AutoAqua in Taiwan. As creators of the Smart ATO Micro, AutoAqua is one of the most well-known and trusted makers of aquarium automation systems in the hobby today. CoralVue has thoroughly tested the Skimmer Sensor to ensure seamless compatibility with the HYDROS platform. The product development team at CoralVue engineered the sensor so it connects with any HYDROS Sense Port using its aviation-style plug for safe operation. No additional power source is needed to run the sensor.

General Information
Hydros aquarium controllers are the next generation of automated aquarium devices. Rather than relying on each individual device’s brain and programming capacity, the Hydros Control units have their own CPU and control capabilities. Hydros Control devices remove the problem of incompatible ports and need to continually add modules to expand your aquarium’s automation system. This new technology is called the Hydros Sense Port. The Sense Port is an entirely new concept in aquarium monitoring technology. A Sense Port is a generic input port that can accept data from numerous different types of sensors. Drive Ports provide 12-volt power for controlling ATO pumps, cooling fans, and other devices. Hydros is the future of automation!
