this is involved in a school project where we have to have a battery/energy buffer to draw power from if our solar panels are not producing enough electricity to power the arduino and its circuit. i want the solar panels to charge up the battery while we will still be able to draw power from the battery.
we are meant to create a weather station to measure stuff like temperature and humidity and send it to a remote server which means that it has to stay outside and the charging mechanism cant rely on us physically pressing a button or flipping a switch on the circuit. any help would be greatly appreciated!
Well, current can't flow into the battery and out of the battery at the same time. But the solar panels and battery charging circuit could produce enough current to power the load and charge the battery at the same time.
Do you have any information on the solar panels, the current draw of your Arduino circuit, and the kind of batteries you will be using?
While the following device may not suit your (currently undefined) needs, it is the sort of thing you should be googling for:
Hi,
you didn't say which model of microcontroller you are using in your project.
If it is 3.3V, use the MCP73831 CI to charge the battery and the AP2112 3.3 CI to power the microcontroller.
