Measuring is knowing with the TechGrow sensors
With the TechGrow S-4 Sensor you have an all-in-one CO2 Sensor that not only measures the CO2 concentration but also the relative humidity and temperature and also detects light. The TechGrow S-4 Sensor has a built-in light sensor which ensures an automatic switch between day and night mode, if it is necessary to run a continuous day program this can be set manually by means of the DIP switch.
In addition, the S-4 Sensor is equipped with a manual calibration function which, if necessary, allows you to calibrate the CO2 sensor yourself in fresh air at 400 ppm (this calibration menu can only be accessed via a CO2 controller). To prevent unwanted calibration, the sensor is equipped with an additional DIP switch.
This sensor is suitable for all TechGrow Controllers and is adjustable in steps of 10 ppm.
