Seeed Studio Grove CO2 Temperature Humidity Sensor SCD30

SKU CH-1D1N-J3E26

Measures CO2, temperature and humidity with NDIR accuracy of ±(30 ppm + 3%) from 400 ppm

  • TypeSensors
  • Measures CO2 with ±(30 ppm + 3%) accuracy
  • Detects carbon dioxide from 400ppm to 10'000ppm
  • Combines CO2, temperature and humidity in one module
  • Compensates for external heat sources with built-in algorithm
  • Connects via digital I2C interface for simple integration

Grove SCD30 Environmental Sensor

The Grove SCD30 is a 3-in-1 module that measures carbon dioxide, temperature and humidity. It uses an embedded Sensirion SCD30 with NDIR technology for CO2 detection. The digital I2C interface and Grove connector make it simple to add to microcontroller projects. Condition is new.

Makers building air-quality monitors

This sensor suits developers who need CO2 data alongside temperature and humidity in a single board. It is not for buyers who require analogue output or a sensor without on-board compensation algorithms. Projects needing a different measurement range or a non-Grove form factor should look elsewhere.

NDIR CO2 accuracy ±(30 ppm + 3%) from 400ppm

The key specification is the CO2 measurement performance: ±(30 ppm + 3%) accuracy across a 400ppm to 10'000ppm range. This figure decides whether the module meets the precision demands of your ventilation or environmental application. The integrated temperature and humidity sensing supports the CO2 compensation algorithm.
