AC Infinity AI Hydro Sensor is a precision water-quality monitoring probe designed to track key nutrient solution parameters in hydroponic and irrigation systems. Manufactured by AC Infinity, this smart sensor measures pH, EC, TDS, salinity and water temperature in real time, helping growers maintain optimal nutrient balance for healthy plant growth.
When paired with compatible AC Infinity AI controllers, the hydro sensor enables automated monitoring, alerts and device control through the AC Infinity mobile app, allowing growers to optimise nutrient dosing and water management with minimal manual adjustment.
Key features
• Tracks pH, EC, TDS, salinity and water temperature in nutrient solutions
• Designed to integrate with AC Infinity AI controllers for automation
• Provides 24/7 water and nutrient monitoring for stable grow conditions
• Supports smart automation such as nutrient dosing or pump activation
• Interchangeable probe design allows easy replacement of worn sensors
• IP68 waterproof rating for reliable operation in water reservoirs
• Compatible with the AC Infinity UIS smart ecosystem and mobile app
What the AI Hydro Sensor does
Maintaining the correct nutrient solution balance is essential for hydroponic plant health. The AI Hydro Sensor continuously monitors water chemistry and temperature so growers can quickly identify fluctuations in nutrient concentration or pH levels.
When connected to an AI controller, the system can automatically trigger equipment such as dosing pumps or irrigation systems based on real-time data, helping maintain a stable nutrient environment and reducing manual monitoring.
