Sensor Module for CO2 and RH/T Measurements

Product catalog summary

Overview: The SCD30 sensor module is designed for HVAC and indoor air quality applications, offering outstanding stability through dual channel compensation for long-term drifts. It provides three sensor signals: absolute carbon dioxide concentration, relative humidity, and temperature, all based on Sensirion’s CMOSens® Technology.

Temperature Sensor Specifications:

Measurement Range: -40 °C to 120 °C
Typical Accuracy: ±0.5 °C (0 – 50 °C)
Repeatability: 0.1 °C
Response Time (t63): >2 seconds

CO2 Sensor Specifications:

Measurement Range: 0 – 10,000 ppm
Accuracy: ±30 ppm ±3% (25 °C, 400 – 10,000 ppm)
Repeatability: 10 ppm
Temperature Stability: 2.5 ppm/°C (0 – 50 °C)
Response Time (t63): 20 seconds

Humidity Sensor Specifications:

Measurement Range: 0 – 100% RH
Typical Accuracy: ±2% RH (0 – 100% RH)
Repeatability: 0.1% RH
Response Time (t63): 8 seconds

Electrical Specifications:

Supply Voltage: 3.3 – 5.5 V
Average Current @ 2 s Measurement Rate: 17 mA
Max. Current: 75 mA

Applications: The SCD30 is suitable for demand-controlled ventilation, HVAC equipment, air conditioners, air purifiers, smart home, and IoT devices.
