S-4 CO2 Sensor (2000 ppm) - With ABC 

Achieve optimal conditions in your greenhouse, indoor grow or hydroponics farm by using this smart sensor as your CO2 monitor. It can also be used an all-in-one sensor for offices, schools, créches, hospitals and storage rooms. Packed with features to help you give your plants the best environment, it is able to measure CO2 concentration, relative humidity, temperature, as well as detect light.

For added convenience, the automatic light sensor gives you the option to enable easy switching between day and night mode! If you’d rather set the sensor manually, then you can use the reliable DIP switch to set it to non-stop day mode.

Equipped with a state-of-the-art Automatic Baseline Calibration (ABC) function, which can be enabled via the extra DIP switch, any zero drift of the infrared sensor can be eliminated to ensure consistent and accurate carbon dioxide concentration measurements.

Additionally, you have the option to manually calibrate the sensor in fresh air at 400ppm by using one of our CO2 controllers. The sensor comes equipped with a dedicated DIP switch in order to prevent unwanted calibration.

The S-4 is fully compatible with most TechGrow controllers
