Sensirion AGSCD4X CO2 GADGETSensor de calidad de aire
Air Quality Sensor CO2 Sensor 5V
Sensirion’s miniature CO2 sensor SCD4x – Breaking the size barrier
The SCD4x builds on the photoacoustic sensing principle and Sensirion’s patented PASens® and CMOSens® Technology to enable unmatched small sensor size combined with high performance. The integrated humidity and temperature sensor, large supply voltage (2.4 V – 5.5 V), the robustness towards external stresses and the adjustable power consumption make the SCD4X ideal for high-volume applications.
The large supply voltage (2.4 V – 5.5 V), the robustness towards external stresses and the adjustable power consumption make the SCD4x CO2 sensor the perfect fit for varying customer needs.
Popular applications include
• Demand-controlled ventilation
• Indoor air quality monitor
• CO2 ventilation alarm / traffic light indicators
• IoT / smart Home
• Agriculture / green housing
• Industrial
The SCD4x CO2 sensor is perfect for demand-controlled ventilation systems to monitor and control CO2 levels. The small size of 10.1 x 10.1 x 6.5 mm3 allows flexibility in board arrangement. Condensation is not an issue as its integrated humidity and temperature sensor will read 100% RHT.
The SCD4x CO2 sensor is ideal for indoor air quality monitors because of it’s size of 10.1 x 10.1 x 6.5 mm3 as well as it’s integrated humidity and temperature sensor. It provides more accurate, faster and smarter feedback of the conditions of a monitored space.
The SCD4x CO2 sensor is the perfect match for CO2 ventilation alarms or so called “traffic light indicators” that indicate when the CO2 concentration in a room is too high and there is a need to ventilate. Especially concerning the spread of viruses, it can remind to take smart actions to keep infection risk low. Its small size allows new innovative designs.
The SCD4x CO2 sensor is the ideal match for smart home systems, as size is key! With the size of 10.1 x 10.1 x 6.5 mm3 the SCD4X allows an easy integration with a best-in-class humidity and temperature sensor included.
The SCD4x CO2 sensor can be also used for agriculture and green housing. Thanks to highly accurate and reliable CO2 measurements, production can be maximized.
The CO2 sensor SCD4x is also the ideal match for industrial applications as industrial air conditioning systems. Thanks to its membrane and small size, the SCD4x is highly dust resistant and has a low influence on airflow.

Additional Notes:
The SEK-SensorBridge allows you to connect suitable Sensirion sensors to a computer. It works hand-in-hand with the SEK-ControlCenter software. There are two ports on the SEK-SensorBridge, allowing you to connect sensors. You can connect more than one sensor to each port, provided that the sensors have different I2C addresses.
Important: For evaluating particulate matter sensors (SEK-SPS30), VOC sensors (SEK-SVM40) and formaldehyde sensors (SEK-SFA30) no SEK-SensorBridge is needed.
