5. Future micPower Development Directions.
Internet of things, IoT, is the future of the development. This makes it possible to view and control the Load Monitor from within a Browser like Google Chrome or Microsoft Edge and many others. This makes it possible to control the Load Monitor from a PC, laptop, tablet or phone. The embedded WEB-server may get updated by ftp transfer.
The physical Ethernet Interface used by IoT communication may also get used to implement Industrial Communication Protocols like MODBUS TCP, PROFINET and others.
Variable speed motor monitoring is another area for future development. The micPower Load Controllers above are all able to measure the frequency of the AC-motor current. When a motor is controlled from a Variable Frequency Inverter the Current in the motor usually becomes sinusoidal, with a frequency proportional to the speed of the motor. The actual motor speed depends on the PWM modulated voltage waveform applied to the Motor and the number of poles in the motor. So it will be possible to add variable speed monitoring without even adding a motor speed sensor.
