TechGrow S-4 CO2 - CO2, Temperature, Humidity and Light Sensor (2000 ppm)

TechGrow S-4 CO2 sensor (2000ppm) is an "all-in-one" unit – it measures CO₂, temperature, humidity and also detects light. It also has an integrated calibration function for calibrating the CO₂ sensor against outside air. The calibration menu is accessible only through a CO₂ controller. It also has a built-in switch to prevent unwanted calibration.

• measurement range: 0 - 2000 ppm

Almost all TechGrow controllers and sensors are compatible with one another, optimizing ease of use and keeping expansion affordable. Recently, TechGrow started offering controllers and sensors separately, so you can mix and match them as needed. This makes it possible to combine three different controllers with one sensor, e.g. a CO₂ controller, a climate controller and Humi Dual, using only an S-4 sensor. All values measured by your sensor can be saved on the TechGrow Datalogger DL-1. To find out which sensor is compatible with your TechGrow controller, refer to your controller manual. Each Pro Series controller displays the current CO₂, temperature and humidity values, and also records min/max values.
