SCD30 CO2, Temp & RH Module | Air Quality Gas Sensor

This SCD30 CO2 sensor module from Sensirion combines three environmental readings. It measures carbon dioxide, temperature, and relative humidity. The built-in humidity sensor and NDIR technology make this SCD30 air quality sensor a good choice for checking indoor air quality with an Arduino or Raspberry Pi. Features and Benefits - NDIR CO2 sensing technology - Gives you steady, correct carbon dioxide readings. They don't change much over time like simpler sensors. - Built-in temperature and humidity sensor - Puts three measurements into one part. This makes your project's design and code simpler. - Automatic Self-Calibration - The sensor adjusts itself using the air around it. This keeps its accuracy without needing you to set it by hand. - I2C digital interface - Connects to your microcontroller with two data wires. This makes the SCD30 CO2 sensor I2C interface easy to set up. Applications - Checking and adjusting ventilation in smart home or office HVAC systems. - Making a desktop device to watch indoor air quality. This helps you know when to open a window. - Adding environmental sensing to IoT projects for recording and looking at data. What It Is This is a Sensor Module designed for air quality monitoring.
