Please note that as of October 24, 2014, the Nokia Developer Wiki will no longer be accepting user contributions, including new entries, edits and comments, as we begin transitioning to our new home, in the Windows Phone Development Wiki. We plan to move over the majority of the existing entries over the next few weeks. Thanks for all your past and future contributions.
Mobile Sensor API
Mobile Sensor API (JSR 256) allows developers to get data from embedded sensors, as well as from sensors connected via infrared, Bluetooth or GPRS. Examples of embedded sensors are accelerometers and sensors giving information of the device state, such as a network field intensity and a battery charge sensor.
