Controller AI+ Sensors – Teach Your Controller to Notice Things
A controller is only as clever as what it can sense. The AC Infinity Controller AI+ already reads temperature, humidity and VPD; these plug-in sensors give it new senses, so it can act on carbon dioxide, soil moisture, water quality and leaks as well. Each one plugs into the AI+ and appears in the AC Infinity app with its own automations, charts and alerts.

| Sensor | What it lets your AI+ do |
|---|---|
| CO₂ + Light Sensor | Track CO₂ in PPM and run fresh-air exchange only when needed, with day/night scheduling |
| Soil Sensor Probe | Monitor soil moisture and saturation and trigger watering devices. IP67, detachable stem, gentle on roots |
| Hydro Sensor | Watch pH, EC, TDS and water temperature 24/7 in reservoirs, hydroponics, ponds and aquariums. Interchangeable probes |
| Water Sensor | Detect leaks or water presence and send alerts. IP68, suction or magnetic mounting |
| Climate Sensor 24ft | A long corded temperature/humidity/VPD probe with a Swiss thermal-alloy head, for spot readings anywhere |
Not just for growers
The soil probe is a gift for anyone who kills houseplants by kindness: it tells you when the pot is genuinely dry. The water sensor guards against overflowing self-watering trays and reservoirs, and the hydro sensor is equally at home on an aquarium or pond.
🌿 Rose's Pro-Tip: only one of each sensor type works on an AI+ at a time. Start with the sensor that solves your most annoying problem, usually watering, and add others once you trust the data.
Requires an AC Infinity Controller AI+ (sold separately).
Pairs well with: Controller AI+, self-watering bases.

Which should I start with?
