Repurpose solar-powered light

Submitted by Jack on Thu, 05/05/2022 - 21:03

I would like to repurpose an inexpensive (IPX5 55 lumen) solar-powered landscape light to power an IoT esp32-based field sensor, eg, soil moisture.

The esp32 would remain in Deep Sleep mode, periodically waking up to take sensor measurements or upload to a mqtt server.

It would have to work during daylight hours. 

How to do this and what other things do I need to consider?

I ask because my brother-in-law 'electronics expert' told me it couldn't be done.

Seems straight-forward to me since I am just replacing one load with a lower load.
