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).
