In order for a device to be able to send data to a computer, the most common way is through the use of a microcontroller. However, this requires the development of a driver for the microcontroller, which is a complicated process. In addition, the development of drivers is made more complicated by the large number of different microcontroller models available on the market.

In order to simplify the process of developing drivers, ODK created the ODK Sensors Framework. This is a tool that allows the developer to create a driver that will work with any device that is compatible with the Android operating system. This is a tool that can be used to develop and test sensor-based applications on a Android device.
