bit of an update on BLE – voltage free switch contact monitor – low power – with contact wetting boost circuit

We are using the TI CC2650STK and have a small development board with our boost circuit. We are using periodic monitoring to have a low average power consumption. Depending on the setup – up to 5 years on a SAFT LS14250 cell.

We have setup a contact state and click counter, and have the data in the advertising, so no connection required to obtain data.

We will put up a board design for this application soon.
