Enocean has introduced its Dolphin wireless system, enabling energy-autonomous actuators and bidirectional communication of sensors.

Enocean Dolphin allows on-demand matching and continuous optimisation of central system features such as energy budget, peripheral functionalities and wireless communication.

The length of wireless telegrams, for example, is minimised dynamically to the data content for transmission.

In programming, only the required software function blocks are saved to memory.

The Dolphin architecture was developed to enable non-proprietary systems to match the demands of different applications.

The modularity of Dolphin's system architecture makes it suited for future demands such as encryption or Meshnet routing.

The bidirectional plug-and-play TCM 300 transceiver module for Enocean wireless systems has half the standby power requirement of its predecessor (2.5 to 3.3 V, receiving approximately 30 mA and transmitting approximately 15 mA).

The 10-bit A/D converter produces greater measuring accuracy and four times the resolution for sensors than its forerunner, the STM 110.

An optional repeater function, activated by a pin, reduces the number of system components needed and simplifies start-up.

The mini-operating system and API enable straightforward programming.

Parameters can be changed using software updates during installation or in operation.

Complex software functions such as SMART ACK (bidirectional wireless transmission), encryption and routing can be integrated as ready macros, maintaining the interoperability of end-user equipment and shortening time to market.

The module offers many ready-programmed operating modes for switching and dimming.

A bidirectional serial interface serves for integration in external logic or an automation system.

The STM 300 is the bidirectional Enocean module for energy-autonomous device applications.

It differs from the TCM 300 through its extensive energy management of miniature converters which harvest energy from differences in temperature, rotation, light or vibration.

The low-power wake-up threshold switch and voltage limiter play an important role in the integrated circuit.

The STM 300 has many basic plug-and-play operating functions, including: three analogue inputs, four digital inputs, configurable wake and presence cycles and wake-up pins.

Enocean's Dolphin system architecture is compatible with earlier Enocean products and installations.

Enocean has also introduced an operating system with an application programming interface (API) that allows application-specific programs to be written in high-level C language.

Enocean has added the Dolphin Studio development environment to the API.

This supports configuration of the various API modules and ensures fast development time.

The command line program integrated in Dolphin Studio controls the programming operation and is easily implemented in fabrication.

Enocean is now also implementing energy-autonomous actuators in its Dolphin-based modules.

For example, actuators of this kind can control heating radiator valves.

They draw their energy through the use of Peltier elements.

SMART ACK allows return messages from self-powered Enocean wireless sensors so that the processor of an actuator can communicate bi-directionally with a central control point.

This allows actuator components to operate on demand.
