EnOcean wireless technology basics in M2M and IoT
The figure depicts typical EnOcean system. As mentioned unlike other wireless systems EnOcean system devices do not require battery for operation. Wireless sensors use motion converters, solar cells and also thermo converters for energy harvesting.
Moreover with efficient energy management EnOcean transmits information with the use of radio with minimum amount of energy. EnOcean protocol stack is modular and versatile and hence customer applications are easily integrated with it.
Typical EnOcean chip will have energy converter, energy management, sensor, microcontroller, RF transceiver and antenna.
