Sensirion SCD30 NDIR CO2 Temperature and Humidity Sensor I2C UART PWM 3.3V-5.5V (400ppm to 10000ppm CO2 Sensor Module)

The Sensirion SCD30 is a high-precision environmental sensor module that combines Non-Dispersive Infrared (NDIR) carbon dioxide sensing with integrated temperature and humidity measurement. Designed for accurate indoor air quality monitoring, it measures CO2 concentrations from 400ppm to 10000ppm while simultaneously providing temperature and relative humidity data. Supporting I²C, UART, and PWM communication interfaces, the SCD30 is easy to integrate with microcontrollers, embedded systems, and IoT devices. Its low power consumption, compact design, and maintenance-free operation make it ideal for long-term environmental monitoring applications.
