EnOcean has developed a new multisensor, the all-round talent among self-powered wireless sensors. In the new original PTM form factor the sensor module supplies data for a wide range of applications in digitized buildings and the IoT.

The integrated solar cell generates all the energy required for operation - both for measurement and for data communication. The gathered energy is stored internally to ensure that the sensor will function even when there is little or no light. This means that the self-powered sensor can be used flexibly in buildings. Moreover, it can easily be configured and commissioned via an NFC (Near Field Communication) interface.

The new STM 550 multisensor family combines temperature, humidity, lighting, acceleration and magnetic contact sensors in a small case. The multisensor is available both for the EnOcean wireless standard and for Bluetooth systems. This makes the sensor particularly attractive for a variety of applications in the IoT and in digitized buildings.

For the first time, EnOcean has transferred the original PTM form factor of its proven PTM switch module to sensors, so the multisensor module fits into all common switch frames. Manufacturers of existing switch solutions based on the PTM module therefore only need to develop new front panels adapted to the respective frame design. The new multisensor is also available as Easyfit product, which allows new applications to be implemented quickly. Thanks to the integrated solar cell, the sensor supplies itself with energy independently and stores it for uninterrupted operation over several days with little or no light. It also sends reports on the internal energy level and the amount of light available on the solar cell. As a result, STM 550 operates completely maintenance-free. Being a wireless product, the multisensor can be flexibly installed anywhere in the room. It can also be integrated directly into a wide variety of assets and therefore can be used exactly where the data is needed: on walls, ceilings, windows, doors, furniture, active devices such as air conditioners, towel dispensers and objects such as printers, copiers, medical equipment or vending machines.

The multisensor has an integrated NFC interface for easy configuration and commissioning. All that is needed is a computer with an NFC reader or an NFC-capable smartphone or tablet. EnOcean's own app "EnOcean Tool" serves as the configuration interface between the multisensor and the smartphone. It can be used to determine important product parameters and to integrate the multisensor into existing systems. The app is available free of charge for iOS and Android.
