Sensor Sense is a free Android app developed by Kristof Jannes that allows users to monitor the output of all the sensors available on their device. The app offers real-time graphs that let you quickly view changes in sensors, and it also allows you to record sensor data and export it as a shareable .csv file.

The app provides detailed information about the specifications of each sensor, including temperature, light, pressure (barometer), humidity, sound, acceleration, gravity, gyroscope, rotation, magnetic field (with compass), proximity, location, speed, battery, battery temperature, WiFi strength, and mobile network strength. However, the availability of sensors depends on your device.

Sensor Sense comes with an intuitive and beautiful material design interface. It also offers widgets for pressure, temperature, and humidity. The app also provides a calibration feature that allows you to calibrate all sensors when needed. Additionally, you can choose between a light and a dark theme with the premium feature.

The app requires the following permissions: location (to display location info), photos/media/files (to save measurements to a .csv file), and microphone (to display sound info). Download this app for free and start exploring the data around you.
