Sensor Logger collects, records and displays data from a wide range of sensors on your phone — including accelerometer, gyroscope, GPS, audio, camera and bluetooth devices. You can also log device properties such as screen brightness, battery level and network state. An intuitive interface allows you to select your desired sensors and preview them live. A tap of a button initiates the recording function, which works even when the app is in the background. You can view and manage recordings within the app via interactive plots. The export functionality conveniently outputs your recordings in a variety of formats, including Zipped CSV, JSON, Excel, KML and SQLite. For advanced use cases, you may also stream data via HTTP or MQTT during a recording session, resample and aggregate measurements from multiple sensors, and create Studies to collect recordings from other Sensor Logger users with ease. Sensor Logger is specifically designed for researchers, educators, and anyone with an interest in collecting or monitoring sensor data on their smartphone. It serves as a toolbox for exploring various fields, including physics, science, technology, engineering, and mathematics (STEM).
