Description
Keep Your Reef’s Water Level & Salinity Locked In With Solid-State Digital Precision
Maintain rock-solid salinity and seamless water-level management with the Red Sea ReefSense ATO Sensor. Designed specifically for Red Sea’s ReefControl Ecosystem (ReefControl Lite & ReefControl Pro), this smart sensor pairs advanced solid-state electroconductivity (EC) water-level sensing with an integrated digital temperature probe in a single, ultra-slim probe body.
Unlike conventional mechanical float switches or optical sensors that can foul from algae, bubbles, or salt creep, the ReefSense ATO Sensor utilizes robust titanium EC probes for fail-safe, instantaneous water-level detection. Whether you are expanding your custom top-off setup or replacing a sensor, this unit delivers real-time monitoring, mobile telemetry, and emergency failsafe alerts directly through the ReefBeat app.
Key Features & Benefits
-
Solid-State EC Water Level Sensing: Built with multi-input titanium probes utilizing electroconductivity (EC) technology to eliminate moving parts, resisting mineral buildup, snails, and optical interference.
-
Dual-Action Temperature Monitoring: Includes a built-in digital thermometer accurate to ±0.1°C, consolidating water level and thermal monitoring into a single port connection.
-
Direct ReefBeat Ecosystem Integration: Connects seamlessly to any universal digital port on your ReefControl Lite or ReefControl Pro controller—no complex wiring or calibration required.
-
Automated Equipment Logic: Leverage your live water level and temperature readings to automate connected 12V DC accessories (such as ATO top-off pumps or cooling fans) or AC equipment via ReefControl Power.
-
Instant Mobile Alerts & Logging: Receive push notifications through ReefBeat if water levels fluctuate abnormally or temperatures stray outside designated safety thresholds.
-
Interference-Free Digital Signal: Onboard digital signal processing converts analog sensor data inside the probe itself, completely eliminating electromagnetic noise (EMI) along the cable run.
