Designed for greenhouses and indoor spaces, it offers programmable CO2 control with a 4.5-meter sensing probe cable and dual modes for plant growth or human comfort. Its relay output supports external devices up to 5A/250V AC, enabling automated CO2 generation or ventilation to maintain optimal air quality and energy efficiency. ## Description Product Description The controller features a programmable output that turns ON or OFF based on the CO2 concentration detected by the external sensor. When CO2 levels fall below the set threshold, the controller can activate a CO2 generator to increase CO2 levels . When CO2 levels exceed the set limit, the controller can activate a ventilation fan to reduce CO2 levels . Plant Mode (Greenhouse/Hydroponics Use) Maintains higher CO2 levels beneficial for plant growth. Activates the CO2 generator when levels are low. Turns off the generator when CO2 reaches the set maximum. Human Mode (Indoor Air Quality Use) Maintains CO2 levels at safe limits for human comfort and health. Turns on the ventilation fan when CO2 levels are high. Turns off the fan once CO2 drops to a safe level. Display & Control Benefits of Auto Day/Night Detection Optimized CO2 Control for Plants – Plants require higher CO2 levels during the day for photosynthesis and lower levels at night. The controller automatically adjusts CO2 regulation accordingly. Energy Savings – Prevents unnecessary CO2 generation or ventilation at the wrong time, reducing energy consumption. Hands-Free Operation- No need for manual adjustments; the system adapts to the environment automatically. Output Power Capacity The controller can switch external devices ON/OFF through its piggyback socket , supporting 5A at 250V AC 10A at 120V AC How It Works The external CO2 sensing probe is equipped with a light sensor that detects whether it is daytime or nighttime . Based on this detection, the controller can automatically switch between different CO2 control settings , ensuring efficient CO2 regulation for various applications.
