I'm using the ADP5090 demo platform for Energy Harvesting on my Bunch WSN nodes. It sometimes works but more often not, as the connection is very unstable. Depending how I connect the Bunch WSN to the ADP5090 board, completely entered or not, with an angle or not, it sometimes works, sometimes not. Is this issue known? What can I do to fix/stabilise this?
The bunch WSN board power consumption is not very small especially in startup. if your connection is not stable, the WSN board may start up frequently so that consumes much more power.
Right, so how to fix this issue?
use a bigger super capacitor
more stable connection
wait the voltage on supercap higher then connect.
