AC Infinity Soil Sensor (for AI+ Controller)

Water From Real Root-Zone Data, Not Guesswork

The AC Infinity Soil Sensor connects to your AI+ Environmental Controller and reads soil moisture and saturation directly in your growing medium. Instead of watering on a hunch, the controller uses this live data to trigger irrigation automatically and hold your substrate in the right range.

Key Benefits

• Accurate root-zone moisture and saturation readings taken from inside the medium, to ±5%
• Automated watering triggers through the AI+ Controller
• 1-second refresh rate for responsive, up-to-the-moment data
• IP67-sealed against liquid and dirt for long-term reliability in the substrate
• Detachable fiberglass stem for secure placement deeper in the pot
• Avoids over- and under-watering, protecting root development and pace of growth

Guessing when to water and getting it wrong?

Watering to a fixed schedule rather than actual medium conditions is a classic cause of overwatering and underwatering, both of which stall roots and slow growth. With a probe reading moisture and saturation in the root zone itself, the AI+ Controller irrigates only when the medium genuinely needs it, keeping conditions consistent.

How to Use

• Plug the sensor into a spare port on your AI+ Environmental Controller
• Insert the stem into your soil or medium near the root zone, using the detachable stem for depth
• Set your target moisture range so the controller triggers connected irrigation automatically
