ZY-STCC4 Digital Temperature Sensor Module STCC4 3-in-1 CO₂ Sensor, Temperature, and Humidity Module for Beskrivelse

The sensor's performance specifications are valid under the following conditions: ambient temperature 25C, relative humidity 50% RH, atmospheric pressure 1013 hPa, powered by a 3.3V supply, and operating in continuous satellite tracking mode 5.

Output Range: The CO concentration output range is 380 ppm to 32,000 ppm.
Measurement Accuracy: Within the range of 400 ppm to 5,000 ppm, whether in continuous measurement or single-measurement mode,
the accuracy is $pm(100~ppm+$10% of reading). This accuracy requires temperature and humidity compensation using the SHT40I.
Digital resolution: 1 ppm
Response : Typical response (T63%) is 20 seconds (measured under conditions where CO concentration changes in a step from 2,000 ppm to 400 ppm)

The STCC4 operates by measuring the thermal conductivity of the air surrounding the sensor. When the air composition changes, its thermal conductivity deviates from the "fresh air" reference value; this deviation is interpreted as a change in O₂ concentration. The "fresh air" composition defined in the manual is: 78% N₂, 21% O₂, 0.93% Ar, 400 ppm CO₂, and H₂O varying with relative humidity. Testing with non-standard gases (such as N₂) will result in measurement errors.
