About this product

The 7Semi SCD43 CO₂, Temperature and Humidity Sensor Breakout  is a compact sensor module for accurate indoor air-quality monitoring. It uses Sensirion’s PASens photoacoustic NDIR technology to directly measure CO₂ levels from 0ppm to 40,000 ppm, with an accuracy of ±(30 ppm + 3% of the reading). It also measures temperature and relative humidity, making it ideal for HVAC systems, smart buildings, indoor air-quality monitors and IoT applications.

Important power note: When powering the board through VCC, the 3V3 pin acts as the regulated 3.3V output with 200mA current rating . Alternatively, the board can be powered directly through the 3V3 pin. Do not apply power to both VCC and 3V3 at the same time.
