Description
The SCD41 is a high-precision CO₂ sensor based on NDIR (Non-Dispersive Infrared) technology, designed for monitoring indoor air quality.
It measures CO₂ concentration in a typical range of 400–5000 ppm, with high stability and accuracy. It also integrates temperature and humidity sensors, used for internal measurement compensation.
Communication takes place via the I2C bus (SDA/SCL), making it easy to integrate with microcontrollers such as Arduino, ESP32 and Raspberry Pi.
It operates with a 2.4–5.5 V power supply, compatible with 3.3V and 5V systems. Its low power consumption and compact form factor make it ideal for home automation and IoT applications.
