EnOcean is the pioneer of energy harvesting and sensor-to-cloud solutions for sustainable Internet of Things (IoT) applications. For more than 20 years, EnOcean has been producing maintenance-free wireless switches and sensors, which gain their energy from the surroundings – from movement, light, or temperature changes. The combination of miniaturized energy converters, ultra-low power electronics, robust radio technology, and open multi-protocol connectivity solutions based on open standards (EnOcean, Zigbee, Bluetooth®, BACnet, Modbus, LON, and IAP) forms the foundation for smart buildings, services, and production processes in the IoT. The sustainable EnOcean solutions are used in building automation, smart homes, LED lighting control, industrial applications as well as for logistics and aviation to optimize the carbon footprint of buildings and spaces. Hardware and software solutions from EnOcean are successfully deployed by leading partners worldwide.
