SENSIRION SCD40DR1 CO2 Sensor

The SCD40DR1 is a compact, high-accuracy CO2 sensor designed for indoor air quality monitoring and smart ventilation systems. Built on Sensirion’s proprietary PASens® photoacoustic sensing technology, it offers a measurement range from 0 to 40,000 ppm with ±(50 ppm + 5% of reading) accuracy between 400 and 2000 ppm. Its small form factor (10.1 x 10.1 x 6.5 mm) is reflow solderable, enabling cost-effective, space-saving integration into various devices. On-chip temperature and humidity sensors improve measurement reliability, while low power operation makes it suitable for battery-powered applications.
