Autopilot’s Digital CO2 Controller with Integrated Sensor is a single-zone environment controller that measures and regulates carbon dioxide using a built-in, low-drift dual-channel NDIR sensor. It supports two operating modes: enrichment (to drive a tank regulator or CO2 generator) and exhaust (to trigger a ventilation fan when levels are too high). The unit monitors and controls 0–5000 ppm with adjustable setpoint and deadband, logs trends for up to 7 days, and includes day/night detection via an integrated photocell that disables enrichment during lights-off. Rated 120 VAC, 60 Hz, 10 A max, it includes a 5 ft power cord and is ETL listed. Designed to mount in the grow space, it eliminates remote probes and simplifies CO2 management.
