Autopilot’s CO2 Monitor & Controller is a single‑zone environment controller for automating CO2 enrichment in sealed grow spaces. It uses a low‑drift, two‑channel NDIR CO2 sensor housed in a remote probe with a built‑in photocell and 15 ft (4.5 m) cable for accurate placement. Users set a target CO2 setpoint and a customizable ppm deadband; the unit then switches connected enrichment equipment to maintain levels. It records and graphically displays CO2 trends by minute, hour, day, and week with adjustable zoom for fine tuning. The measurement range is 0–5000 ppm. Physical dimensions are 14.5 × 19.5 × 4.4 cm and weight is 0.7 kg. A green status LED indicates operating state. Suitable for day/night detection through the probe’s photocell.
