2.4 GHz transmitter powered by a button press

EnOcean has added to its offering of batteryless devices for the “Internet of Things” with a prototype of a self-powered wireless transmitter in the worldwide 2.4 GHz ISM band

Powered by EnOcean’s ECO 200 electro-mechanical energy converter, the press of a button is converted into a wireless signal, enabling data communication without cables and batteries. The prototype also uses an additional NFC radio (Near Field Communication) to pair the transmitter functionalities with the receiver using a smart phone. This opens up many new ways for system developers and users to integrate batteryless components into their network.

“The prototype of the 2.4 GHz transmitter shows that, based on our proven module platform and new chip generations, we are able to power several existing radio protocols with energy harvesting. This opens the door to a realm of new applications for EnOcean and is particularly interesting for self-powered consumer applications that already use 2.4 GHz radios. For example, push messages from a personalised alert button to the cell phone of a care worker,” says Matthias Poppel, Chief Operation Officer, EnOcean GmbH.

EnOcean will show the prototype, along with developer kits for its established IoT products, at the embedded world 2014 exhibition (February 25-27, Nuremberg), on stand 1-170 (HY-LINE Computer Components).
