A free program for Android, by Steppschuh.

Sensor Data Logger plots real-time charts. It displays the values of selected sensors – which includes generic sensors like acceleration, magnetic field, and gravity, as well as specific device sensors like double tap, step detection, and temperature.

With its Android Wear support feature, the app enables users to stream data from all sensors of connected Android Wear devices in real-time. This means users can monitor sensor data from their smartwatches and even from multiple wearables simultaneously, and provides comprehensive insights into various sensor readings.

While the app currently supports a wide range of tested sensor types, the developers are actively working on adding more features. An upcoming release is set to include the ability to record and export the collected data to JSON or CSV files. Sensor Data Logger is an open-source project, and users can contribute to its development by visiting the GitHub repository and submitting pull requests.
