This sensor measures CO2, temperature, humidity and detects light simultaneously. The sensor is also equipped with a built-in function for calibration of the CO2 sensor against the outside air. The calibration menu is only available via a CO2 controller. It is also equipped with a built-in switch to prevent unwanted calibration. Available in: 0 - 10,000 ppm. All TechGrow controllers and sensors (except the temperature sensor) can be interconnected to ensure optimal user performance. It is possible to connect all controllers to each other so that you can control your entire climate using the TechGrow S-2 sensor. Since each device has 3 UTP connectors, it is possible not only to connect all the controllers, but also to connect, for example, one data detector DL-1 or SMS detector with AM-T. The sensor can be connected to any UTP port. Ordinary TechGrow sensors are the same as TechGrow Pro series sensors and can therefore be used for Pro Series controllers.
