Hey Mark - thought I’d reach out and ask you more about your project! You mentioned that it was awarded a National Academy of Medicine grant? Sounds pretty cool, would be interested in knowing more about it!
@mark_pdx Thank you so much for your contribution! The Pull Request has been merged into the DeviceOS develop branch, and the long range BLE feature will be making it into a DeviceOS release soon.
@mariano @gusgonnet @schaud Thank you all for your support in making this happen!
The system’s purpose is to support seniors who want to continue living independently. We designed custom BLE wireless sensors that detect motion of a refrigerator door, medication container, or other indications of normal activity, as well as monitoring indoor temperature. We found BLE 5 Coded Phy necessary to get reliable coverage throughout a residence. The Particle Boron serves as a BLE 5-to-Cellular gateway, relaying data from the 2 or 3 sensors in the elder’s home to the cloud. A companion app lets the seniors connect with each other. If normal activities are not taking place (or if excessive heat/cold is present) the senior’s peers are notified in the app, so they will check in on them.
Our prototype sensor looks like this:
The Gateway plugs into an ordinary USB wall charger, and the whole assembly basically looks like a night light. Photo:

oh wow, I’m speechless. What a great, noble, and useful project you are developing.
Thank you for posting details about it!
Gustavo.
This is so great!
Hi Mark, I'm curious to know what IC did you use for the remote sensors.
If you can, please let me know.
Thanks!
Gustavo.
The remote sensors use the Laird 654 series Bluetooth module, based on the nRF52840 (Laird PN 451-00001). That Laird module includes a trace antenna and is FCC certified. The actual motion sensing is done with an LIS2DH12. We just had 75 of our PCBs fabricated and assembled at PCBWay in China, and I’m about to open the box and see how they check out.
thank you for the details, and that above is an amazing achievement! congrats!
