Inkbird CO2 Controller for Grow Rooms ICC-500T with S01 Sensor — Dual Outlets & Digital Display

The Inkbird ICC-500T is a dual-outlet CO2 controller with a detachable S01 CO2 sensor that monitors and automatically maintains target CO2 (ppm) levels for indoor grow rooms and CO2 generators.

Designed for hobbyist and small commercial growers, the ICC-500T pairs a clear digital controller with an external S01 sensor so you can measure ambient CO2 and trigger equipment—CO2 generators, regulators, or exhaust fans—when levels cross set thresholds. The unit displays current and setpoint ppm values, supports calibration and audible alarms, and includes two switched outlets so you can automate both CO2 input and ventilation without extra relays.

How does the ICC-500T keep CO2 at the level I set?

The controller continuously reads CO2 from the included S01 sensor and compares it to the programmed target. When the measured ppm falls below or rises above your setpoint, the controller activates the appropriate outlet to add CO2 or run ventilation, then stops once the target is reached.

• Programmable ppm setpoint with automatic on/off control
• Two outlets: WORK1 for CO2 source, WORK2 for exhaust/ventilation
• Real-time digital display of measured and desired ppm
• Supports calibration and has built-in alarm alerts

Will the S01 sensor work accurately inside a small grow tent?

The detachable S01 sensor is designed for home growing and HVAC use, providing stable CO2 readings suitable for tents and small rooms. For best accuracy place the sensor where it reads representative ambient air away from direct CO2 streams and recalibrate periodically per the manual.

• S01 sensor suited for indoor, tent, and HVAC environments
• Sensor placement tips: avoid direct gas jets and near fans
• Calibration feature to maintain long-term accuracy
• CE & FCC certification for electrical and radio compliance

How do the dual outlets simplify my grow-room setup?

The ICC-500T’s two independently switched outlets let you manage CO2 enrichment and exhaust from one device, eliminating extra controllers or relays. Plug your CO2 regulator or generator into WORK1 and connect an exhaust fan to WORK2 so the controller can both add CO2 and clear excess automatically.

• WORK1 dedicated for CO2 source (regulator or generator)
• WORK2 designed for exhaust fan or ventilation control
• Automatic sequencing: enrich, then ventilate when needed
• Plug-and-play wiring reduces installation time and complexity

What safety and reliability features are included?

The ICC-500T includes alarm functionality and supports sensor calibration to help catch drift or unexpected CO2 spikes. CE and FCC certification indicate compliance with common safety and electromagnetic standards; still follow local regulations for CO2 use and install with adequate ventilation.

• Audible alarm for out-of-range CO2 readings
• Calibration support to maintain sensor accuracy over time
• CE & FCC certified components for electrical and radio safety
• Clear digital display for quick status checks

Who is this for: The Inkbird ICC-500T with S01 sensor suits home growers, small commercial operators, and hobbyists who want automated CO2 management without complex wiring. It’s useful for anyone running tents, closets, or compact grow rooms who needs predictable CO2 control, dual-device automation (CO2 source plus exhaust), and easy-to-read monitoring with periodic calibration capabilities.
