briidea CO2 Monitor and Controller Newest CO2 Controller with Remote Sensor Photocell for Day/Night Control Programmable Function to Save CO2 for Grow Room Greenhouse

- Smart CO2 Control for Plant Growth: Covers all CO2 functions to meet your full growing needs. In light-sensing mode, CO2 runs only in daylight and shuts off automatically when dark to save energy. In “Off” mode, it still monitors the environment while the load stays completely off. - Time-Based Smart Control: Featuring 6 standalone programs, you can set start times for each period. Plants need different CO2 levels in the morning, noon, and evening, so you can set precise ppm for each period, ensuring efficient uptake while reducing CO2 waste and making every dose count. - Reliable in Humid Environments: Dual-channel, low-drift NDIR CO2 sensor delivers precise ppm readings and stays stable even in high humidity, resisting corrosion and rust for long-lasting use. The 6.56 ft sensor cable allows flexible placement anywhere in your grow space. - Safe and Reliable Under High Loads: Supports up to 15A and 1800W with UL-certified components and a waterproof housing for safe, stable operation. Even during a power outage, the CO2 controller automatically remembers your settings, keeping your grow schedule on track. - Easy Operation: The clear screen makes setup simple, and the piggyback plug keeps cords neat. The controller provides “Greenhouse” and “Ventilation” modes. Simply connect your CO2 generator or exhaust fan, and it automatically turns the load on or off to keep your plants in optimal conditions.
