DataLogger IoT
Automatically log sensor data to the cloud without writing a single line of code.
The SparkFun DataLogger IoT is your ultimate plug-and-play solution for capturing data. Whether you need wireless cloud integration or local CSV/JSON files, the DataLogger IoT automatically detects, configures, and logs an expansive and ever-growing list of Qwiic sensors and GNSS receivers out of the box.

Why Choose a No-Code, Wireless Data Logger?
Most data logging solutions require firmware development, libraries, and debugging.
The DataLogger IoT doesn’t! It stands above other logging options by:
- Automatically detecting connected sensors.
- Logging data instantly on startup.
- Configuring through a simple serial menu
- Working with cloud platforms and local storage
Simply put, the DataLogger IoT removes one of the biggest bottlenecks: setup time.
