MOTION SENSOR BOARD Manual All Mikroelektronikas development systems feature a large number of peripheral modules expanding microcontrollers range of application and making the process of program testing easier. In addition to these modules, it is also possible to use numerous additional modules linked to the development system through the I/O port connectors. Some of these additional modules can operate as stand-alone devices without being connected to the microcontroller. MikroElektronika Additional boardMotion Sensor Board The Motion Sensor additional board features a sensor AMN11112 detecting infrared (heat) emission of bodies. It detects changes in infrared spectrum. When some changes are detected the microcontrollers pin is fed with a logic one (1). For connecting the additional board to a development system or a device containing a microcontroller it is necessary to use pads.
