AC Infinity Hydro Sensor (for AI+ Controller)

Track Your Nutrient Solution Without Constantly Dipping the Tank

The AC Infinity AI Hydro Sensor plugs into your Controller AI+ and continuously monitors your reservoir's pH, EC, TDS, salinity and water temperature from a single IP68 waterproof probe. Instead of dipping a handheld pen at feed time and hoping nothing drifted overnight, you get live readings the controller can log, chart and act on.

Key Benefits

• Five readings from one probe: live pH, EC, TDS, salinity and water temperature in your reservoir
• Fully waterproof: IP68-rated for permanent submersion in the tank
• Feeds the Controller AI+: data logging, charts and automated alerts when a value drifts out of range
• Interchangeable probes: worn sensor tips swap out quickly to cut downtime and long-term cost
• Calibration solutions supplied: pH 4.00, 7.00 and 10.01 plus EC 84 uS/cm, 1413 uS/cm and 12.88 mS/cm references

Catching pH and EC drift before it stunts roots

In DWC, RDWC and other recirculating systems the solution is the only thing feeding the plant, so a pH swing or a climbing EC quietly locks out nutrients and stresses roots long before the leaves show it. Continuous readings let the AI+ flag the problem, or trigger connected kit like a chiller, the moment conditions move off target rather than at your next manual check.

How to Use

• Calibrate the pH and EC probes using the supplied reference solutions before first use.
• Connect the sensor to a UIS port on your Controller AI+.
• Submerge the probe in the reservoir, keeping it in flowing solution and away from the return.
• Set your target pH, EC/TDS and water temperature ranges in the app for alerts and automation.
• Re-calibrate periodically and replace worn probe tips to keep readings accurate.
