Bluetooth low energy: IoT Sensors

Poland-based connected home hardware and software manufacturer FIBARO has selected Nordic Semiconductor’s nRF52832 Bluetooth® low energy System-on-Chip for its range of Apple HomeKit-compatible Motion, Door/Window and Flood Sensor solutions. Incorporating an accelerometer, light and temperature sensor, the FIBARO Motion Sensor not only detects movement and vibrations, but also measures the light intensity and temperature in a room. The IoT Sensors also allows users to monitor the duration someone spends in a room. When installed at the home’s entrance, it can also count how many people enter or exit the building.

With a size of 76 by 17 by 19mm the sensor can easily be installed on any door or window and can also be integrated with other Apple HomeKit-compatible devices – for example to prevent heating or air conditioning systems starting while a window is open. All the sensors employ Nordic’s nRF52832 SoC to provide the Bluetooth low energy wireless connectivity between the sensors and Smartphones with iOS Bluetooth 4.0. The Motion and Flood Sensors each employ one 3V CR123A, while the Door/Window Sensor employs one 3.6V ER14250 battery, both providing the sensors with up to two years of standard operation between replacement. This is possible due to the low power characteristics of the Nordic nRF52832 SoC.

Our sensors were originally based on Z-Wave, but we wanted to reach mass market customers who do not need a dedicated gateway, and only require a smartphone or tablet so we released an additional line of HomeKit enabled products.

says FIBARO CEO, Maciej Fielder

We were attracted to Nordic’s Bluetooth low energy solution as it perfectly suited our need for low power consumption, longer battery lifetime, and Apple HomeKit compatibility. This is our first time working with Nordic, but we have been impressed with the technical support, the support provided by the wider Nordic Semiconductor community, and the quick response time to our questions.
