Smartphones and tablets are packed with sensors. Normally they’re used by apps or the phone itself, but now Android users can take advantage of their mobile device’s light sensor, microphone and accelerometer to gather and record data with the help of Google and Exploratorium’s new Science Journal app.
Science Journal indicates the amount of light, sound and acceleration in a given axis using either an audio feedback or with a graph. You can then record your results and perform multiple runs to verify your findings. Skip to 0:52 in YouTuber play button’s video below to see the app’s interface:
Science Journal can also obtain data from other devices, such as an Arduino computer, over Bluetooth. To build on the app’s capabilities, Google partnered with several electronics and maker shops to create beginner kits. These kits make it easier to appreciate what you can do with the data you gather as well as different ways of obtaining information. For instance, SparkFun’s kit lets you build a wind spinner and also comes with a light sensor and a temperature sensor.
