S-4 CO2 sensor

Achieve optimal conditions in your greenhouse with the smart S-4 Sensor 2,000 ppm from TechGrow. This all-in-one sensor measures the CO2 concentration, relative humidity and temperature in your room, and detects light.

The built-in light sensor enables automatic switching between day and night mode. If desired, you can manually set the light sensor to a non-stop day mode by means of a DIP switch.

Moreover, the S-4 Sensor 2,000 ppm has a manual calibration function that allows you to calibrate the CO2 sensor in fresh air at 400 ppm, if necessary (this calibration menu can only be accessed via a CO2 controller). To prevent unwanted calibration, the sensor is equipped with an extra DIP switch.

The S-4 Sensor 2,000 ppm is compatible with all TechGrow controllers, and adjustable in steps of 10 ppm.
