Solar power for MKR WIFI 1010

Hi all,

I’m attempting to create a weather station in order to collect data for a machine learning project. Seen as the 1010 has a built in LiPo charging circuit, I’m thinking that I will be able to use that to wire in an 18650. Then use a solar panel and a voltage regulator into the USB port to charge the battery. Am I along the right lines here? Or do I still need a solar charging circuit? I’d also like to be able to use the output of the solar panel as a sensor.


Did you receive some information regarding to you issue?

I’m attempting to create the same project like you

I have also been researching this idea. I cant see any problem with it? Anyone else had experience?

I, originally, built a solar powered weather station using 186650 batteries. It worked but is not hands free. I had to change the batteries once every 3 or 4 months and does not work when temps fall below 33F.

I switched to using a LiFePo4 battery with a PWM charge controller, been running for 1.5+ years and I do not mess with it.

The solar panel is not a sensor. The solar panel is a current device not a voltage device.

I managed to set up the solar power system exactly how I wanted it. I wired two 5v panels in series and used a voltage regulator to drop it down to 5v. I also wired in a hall effect current sensor and a voltage divider to measure the voltage. The two panels pretty reliably powers the board via usb port during the day. Have yet to wire in the battery though.
