Nordic provides a smartphone app that is able to interact with the beacon. The app detects the beacon and will display an image or open a URL when the phone is within a chosen range based on signal strength.
The environment in the video was about 1000 lux. At this light level, the LL200-3-37 panel provides more than enough power to run the beacon. In fact, this same setup was tested down to 200 lux using even less solar.
The beacon used stock settings, but adjusting the broadcast range, increasing advertising period, and regular sleeping could make this device even lower power.
The Solar Development Kit makes prototyping and experimenting with indoor solar simple. Just plug and play.
It handles the energy harvesting, storage and provides a regulated adjustable output to power external devices.
Beacons will play a significant role in the emerging IoT world. To make these new systems sustainable we need to find ways to extend battery life or replace the battery completely.
Energy harvesting, especially ambient light collection, can provide the power needed to maintain these systems indefinitely.
PowerFilm can work with you to develop the optimal solar solution for your application.
