Sensor Logger

Sensor Logger: A Complete Tool for Mobile Sensor Data Collection

Sensor Logger is a versatile mobile application that turns your smartphone into a sophisticated data recording device. It allows you to capture and analyze measurements from over a dozen built-in sensors, including accelerometer, gyroscope, GPS, microphone, and camera. With one-tap background recording and live previews, this sensor logging app simplifies the process of gathering high-quality data for research, education, or personal projects.

Real-Time Monitoring and Background Recording

The app provides live plots and numeric readings for every active sensor, making it easy to validate data quality on the fly. Background recording works seamlessly even when the phone is locked or other apps are open, enabling uninterrupted data collection during long experiments or field trips. This real-time sensor monitoring capability is essential for users who need to track changes without constant interaction.

Flexible Export and Advanced Data Management

After recording, Sensor Logger supports exporting data in multiple formats such as Zipped CSV, JSON, Excel, KML, and SQLite, catering to different analysis workflows. Users can resample and aggregate measurements from multiple sensors, or stream data via HTTP or MQTT for live integration with other tools. The ability to combine datasets and add timestamped annotations further streamlines data processing and interpretation.

Privacy-First Design and Wear OS Support

All recordings stay on the device by default, ensuring complete privacy and control over your data. The app also extends to Wear OS smartwatches, allowing users to log heart rate, wrist motion, and location directly from their wrist. This seamless integration between phone and watch makes Sensor Logger a comprehensive solution for mobile sensor data collection, suitable for researchers, educators, and STEM enthusiasts alike.
