The radio-based PTM 215B switch module can be trained through direct contact with NFC-capable devices without any manual actuation.
Energy harvesting technology developer EnOcean has released its first energy-harvesting wireless modules for 2.4GHz BLE (Bluetooth Low Energy) systems, which complement the existing EnOcean wireless technology in the sub-1GHz band and ZigBee wireless products in the 2.4GHz frequency band.
The first product in the EnOcean 2.4GHz BLE portfolio is the battery-less PTM 215B switch module, which also comes with an NFC function for pairing and set-up, making it easier to train and configure the switch. The PTM 215B is based on the established form factor of the PTM 21x module, invented by EnOcean, and can be integrated into a large number of existing switch designs. The switch is also available as a white label end product. EnOcean aims to enable product manufacturers to develop reliable and self-powered solutions on the 2.4GHz frequency band for use in smart homes and modern light control all over the world.
The radio-based PTM 215B switch can be trained through direct contact with NFC-capable devices without any manual actuation. A number of parameters can also be configured automatically, permitting, for example, protocol data to be modified or additional information to be transmitted, such as group assignments. New devices can thus be integrated into existing systems, substantially reducing their susceptibility to faults.
In addition to the radio-based switch module, the 2.4GHz BLE portfolio from EnOcean also includes white label end products: energy harvesting wireless single-rocker (ESRP) and dual rocker (EDRP) switches for the American market. Solar-based sensor modules will be added to the switch module in 2017, including a door and window sensor, a temperature/moisture sensor and a light sensor. The switches use kinetic energy harvesting; that is, the mechanical action of the switch's operation is used, by way of coils and permanent magnet, to generate sufficient power to complete the wireless transaction.
EnOcean has also disclosed a change in its branding for energy harvesting wireless modules; the company will market its energy harvesting wireless modules and white label products under the Dolphin brand, with the tag line, "Dolphin – Self-powered IoT by EnOcean."
The Dolphin portfolio includes energy harvesting wireless modules for use in building automation and smart homes with EnOcean wireless technology on the sub-1GHz band: "868MHz EnOcean" for Europe, "902MHz EnOcean" for North America and "928MHz EnOcean" for Japan. The Dolphin portfolio also contains wireless modules for ZigBee and BLE systems on the 2.4GHz band, which can be used globally in smart homes and for modern light control.
