EnOcean GmbH is the developer of the patented energy harvesting wireless technology marketed under the Dolphin brand. Headquartered in Oberhaching, near Munich, the company produces and markets self-powered wireless sensor solutions for batteryless applications in the Internet of Things, which are used for building and industrial automation, smart homes and LED light control. The EnOcean products are based on miniaturized energy converters, ultra-low power electronics and robust radio technology in open standards. Leading product manufacturers have been relying on EnOcean wireless modules for their system solutions for the past 15 years and have installed the products in several hundreds of thousands of buildings around the world. 

The battery-free Internet of Things

The Dolphin modules use the energy harvesting principle, in which energy is obtained from the surroundings, to supply self-powered wireless sensor networks. The modules are based on miniaturized energy converters that convert motion, light or temperature differences into electrical energy. Together with an efficient energy management system, the energy harvesting technology facilitates communication between maintenance-free IoT devices based on open wireless standards, such as EnOcean, ZigBee and BLE. The solutions are used in building automation, smart homes, LED light control systems as well as industrial applications.

Networked devices form the basis of the Internet of Things. They process large volumes of sensor data to make our everyday lives easier, safer and more comfortable. EnOcean´s Dolphin modules are a key component of this extensive network: self-powered, wireless sensors that provide reliable sensor data for IoT systems.

Self-powered wireless sensor networks increase system capacity by reducing outages caused by batteries, which means less maintenance work is required. They also help conserve resources and permit sustainable solutions, since fewer cables and batteries are needed. Batteries, in particular, are expensive to maintain, harm the environment and have to be disposed of regularly.

The Dolphin portfolio from EnOcean for maintenance-free wireless sensor solutions

EnOcean GmbH will continue to expand its Dolphin product portfolio. In October 2016, EnOcean launched energy harvesting wireless modules for use in ZigBee and BLE systems on the 2.4 GHz band alongside the established sub 1 GHz EnOcean wireless technology. Thanks to the low power consumption of the EnOcean technology, the batteryless sensors and switchers are perfectly suited to use in smart buildings.

The product lines "868 MHz EnOcean" for Europe, "902 MHz EnOcean" for North America and "928 MHz EnOcean" for Japan consist of batteryless, radio-based switch, sensor and receiver modules as well as various tools. They are based on the EnOcean wireless standard introduced by the EnOcean Alliance (ISO/IEC 14543-3-1X) on the sub 1 GHz band, which has proven to be a resounding success in building automation and smart homes, due to its high reliability and a radio range of up to 30 meters. Standardized sensor profiles help ensure the interoperability of more than 1,500 products from the EnOcean ecosystem, which makes it possible to develop interoperable system solutions.

The Dolphin portfolio also includes the "2.4 GHz ZigBee" product line with energy harvesting wireless switch modules as well as a wireless receiver for ZigBee systems in the 2.4 GHz band, which can be used in smart home applications all over the world. Moreover, the "2.4 GHz BLE" portfolio includes a wireless switch module for BLE systems for modern light control. Radio-based 2.4 GHz BLE sensors will also be available, starting in 2017.


EnOcean is currently working on new energy converters that are able to generate sufficient energy from slight vibrations or temperature differences. Thanks to further miniaturisation of energy converters and electronic components, EnOcean is opening up completely new areas of use to realize energy-efficiency solutions.

Andreas Schneider, CEO: "Battery-free wireless sensors will make an entrance into many different areas of our lives. Whether at home, at the office, or during our precious leisure time – everywhere, we find new possibilities of switching things or recording states: No time-consuming expensive installation, highly efficient use of limited resources. – The pleasure we derive from innovative solutions keeps our team together and will also fascinate you!"
