The SparkFun DataLogger IoT - 9DoF is a sophisticated data logger that comes with pre-installed programming to automatically log data from IMU, GPS, and a variety of pressure, humidity, and distance sensors. This device eliminates the need for writing any code as it automatically detects, configures, and logs data from Qwiic sensors.
The DataLogger IoT is specifically designed for users who need to capture extensive data in CSV or JSON format for their larger projects. The data can be saved to a microSD card or transmitted wirelessly to the user's preferred Internet of Things (IoT) service.
