CO2 sensors

The TechGrow S-2 CO2 sensor measures the CO2 level in your room and detects light. The internal non-dispersive infrared (NDIR) sensor from Senseair, the trusted market leader in CO2 measurement, tells your controller the CO2 level and shows the duration and volume of CO2 dosing. This ensures the best growing conditions for your plants. The built-in light sensor allows automatic switching between day and night mode. This CO2 sensor also has a switch to bypass the light sensor; the sensor then behaves as if it constantly detects light, which allows CO2 to be dosed in the dark.The S-2 CO2 sensor also has an integrated calibration function for fresh-air calibration (400 ppm). The calibration menu is only accessible via a connected CO2 controller. To prevent unwanted calibration, this CO2 sensor has a built-in switch.The S-2 CO2 sensor is available in two versions, 0-2000 ppm and 0-10000 ppm, and is compatible with various TechGrow CO2 controllers. The S-2 CO2 sensor 10000 ppm is only compatible with a T-1 CO2 controller with software version 2.0.Product features- Measures the CO2 concentration in your room.- Detects light via the built-in light sensor- Allows automatic switching between day and night mode.- Option to set the built-in light sensor manually to day mode for a non-stop day programme.- Calibration with calibration gas (TechGrow only)

Create the right CO2 conditions in your greenhouse with the S-2 sensor 2,000 ppm from TechGrow. This sensor measures the CO2 concentration in your room accurately using a non-dispersive infrared sensor (NDIR sensor). The built-in light sensor allows automatic switching between day and night mode. If you wish, you can set the light sensor manually to a non-stop day mode via a DIP switch.The S-2 sensor 2,000 ppm also has a manual calibration function that lets you calibrate the CO2 sensor in fresh air at 400 ppm if needed (this calibration menu is only accessible via a CO2 controller). To prevent unintended calibration, the sensor is fitted with an additional DIP switch.The S-2 sensor 2,000 ppm is compatible with the T-Micro CO2 controller and the T-1 Pro CO2 controller from TechGrow and can be set in steps of 10 ppm. Product features: - Measures the CO2 concentration in your room.- Detects light via the built-in light sensor- Allows automatic switching between day and night mode.- Option to set the built-in light sensor manually to a non-stop day mode.- Manual calibration & test of the CO2 sensor- Calibration with calibration gas (TechGrow only)- Very accurate measurement thanks to the NDIR sensor (non-dispersive infrared sensor)- Measuring range: 0 - 2,000 ppm- Adjustable in steps of 10 ppm- Measuring rate: every second- 1 UTP port- Compatible with T-Micro and T-1

The TechGrow S-4 all-in-one sensor measures the CO2 level, temperature and humidity in your room and also detects light. You can connect this sensor to several TechGrow controllers – a unique combination that gives you complete control! The internal non-dispersive infrared (NDIR) sensor from Senseair, the trusted market leader in CO2 measurement, tells your controller the CO2 level and shows the duration and volume of CO2 dosing. Temperature and humidity are also measured with a high-quality precision sensor. This ensures the best growing conditions for your plants.The built-in light sensor of the S-4 all-in-one sensor allows automatic switching between day and night mode.
