The T-Micro is a digital device designed to measure and regulate CO₂ levels in growing spaces. It's the smallest and most complete CO₂ controller of its series, perfect for maintaining an optimal environment for plant growth. It can be connected to CO₂ generators of many types to increase the levels of this gas in your grow tent, thus plants can multiply their bud production.

Special Features of the TechGrow T-Micro CO₂ Controller

  • Plug & Play Device: This controller is incredibly easy to install and use. Its Plug & Play design makes it suitable for a variety of spaces, from small grow rooms to large greenhouses, simplifying CO₂ management no matter the size of the area.
  • External CO₂ Sensor by SenseAir®: The T-Micro uses an external sensor manufactured by SenseAir® (not included), a Swedish company recognized in the field of CO₂ measurement. These sensors are known for their high accuracy, ensuring reliable and consistent measurements, essential for proper climate control of the grow space.
  • Integrated Calibration Function: A distinctive feature of the T-Micro is its ability to calibrate itself with respect to the outside air. This ensures that CO₂ measurements are accurate and reliable, which is fundamental for properly adjusting CO₂ levels in the grow space.
  • Customizable CO₂ Adjustment: The CO₂ range is adjustable between 300 and 2000 ppm, allowing growers to set the optimal level of CO₂ according to the specific needs of their plants.
  • Continuous Measurements: The sensor performs measurements every second, offering constant and updated monitoring of CO₂ levels, which is crucial for reacting quickly to any changes in the grow environment.
  • Automatic CO₂ Emission Control: Through a 230 V relay, the controller can automatically switch the CO₂ emission source (like a generator or a cylinder) on and off, facilitating efficient management of CO₂ levels.
  • Memory in Case of Power Outages: In case of power interruptions, the controller has memory for reset and hysteresis, ensuring that previous settings are maintained and normal operation resumes once power is restored.
  • Automatic Voltage Detection and Connection Problems: Capable of automatically detecting voltage between 110 V and 230 V, and identifying broken wires or bad connections, this controller offers safe and reliable operation.
  • CO₂ Dosing LED Indicator: An LED diode clearly informs whether CO₂ is being dosed, providing a quick and simple visual verification.
  • Integrated Light Sensor: The external sensor comes with a light sensor, allowing the controller to automatically switch between day and night settings, optimizing the use of CO₂ according to light conditions.
  • Standard Connection and Modularity: The sensor connection is made using a standard network cable (UTP) of 5 meters, offering flexibility in installation. Additionally, the controller and sensor are available separately, and can be connected to the TechGrow AM-T SMS module for remote monitoring.
