Product Description
|
HVAC and Indoor Air Quality Sensing Solution Only 35x23x7mm, the SCD30 is a new CO2 and RH/T sensor module offering dual-channel detection for superior stability, ±30ppm +3% accuracy and a 400–10,000ppm measurement range. It's fully calibrated and linearized with UART or I2C digital interface. |
CMOSens® Technology for IR detection enables highly accurate carbon dioxide measurement at a competitive price.
Along with the NDIR measurement technology for CO2 detection, a best-in-class Sensirion humidity and temperature sensor is also integrated on the same sensor module. Ambient humidity and temperature can be outputted by Sensirion’s algorithm expertise through modeling and compensating of external heat sources without the requirement for any additional components. Thanks to the dual-channel principle for the measurement of carbon dioxide concentration, the sensor compensates for long-term drifts automatically by design. The very small module height allows easy integration into different applications.
Carbon dioxide is a key indicator of indoor air quality. Thanks to new energy standards and better insulation, houses have be-come increasingly energy efficient, but the air quality can deteriorate rapidly. Active ventilation is needed to maintain a comfortable and healthy indoor environment, and to improve the well-being and productivity of the inhabitants. Sensirion’s SCD30 offers accurate and stable CO2, temperature and humidity monitoring. This enables customers to develop new solutions that increase energy efficiency and simultaneously support well-being.
For more detailed information, please have a look at the preliminary datasheet.
