Presented paper deals with the capture and monitoring of the measurements on analog and digital inputs' microcontroller. These readings are then processed and evaluated in the PDA. The mobile application allows you to visualize and store the measured values, statistical evaluation, etc. On the basis of preset values and conditions, it can be switched back and relay outputs. Communications between the hardware interfaces and mobile devices (not only mobile) are based on Bluetooth technology. The application for mobile devices was developed with Visual Studio 2008 by Microsoft.
