Arduino Uno Solar Battery Charger ? Answered
Hello everyone. Newbie here.
My project is to make an environmental monitoring system that will be battery powered and charged using solar energy, when the system is not in use. The components I am using are listed below for reference.
1. Solar Panel http://bit.ly/2zimtCj
2. Rechargeable 9V Battery http://bit.ly/2DxPRma
3. Uno Rev 3 http://amzn.to/2DxVCQP
4. SD Module http://bit.ly/2DyDFl9
5. Grove Dust Sensor http://bit.ly/2Caxx6z
6. Grove Temp & Humidity Sensor http://bit.ly/2ybWbxG
7. Grove Light Sensor http://bit.ly/2Cj3Xem
8. ESP8266 Transceiver http://bit.ly/2zN3kEL
9. Grove Air Quality Sensor http://bit.ly/2khVUah
All the components operate at 5v with the exception of the ESP8266 which is 3.3v. I have been looking at different methods of powering the system and noticed people using LiPo batteries. I'm aware that you shouldn't let there voltage drop too low and something about voltage regulators and boost converters that might be needed.
Based on my system can anyone recommend the best method of powering everything using batteries and charging it through solar energy.
I'm fairly new to the Arduino Eco system and this kind of work in general, so any help would be greatly appreciated. Thanks in advanced.
