- Solar panel (with a maximum output current of 2100 mA and an output power of 25 W; Output voltage - 5 V). These parameters are stated on the seller’s website and may differ from reality.
- development board NodeMCU v2
- Raspberry Pi 3 Model B +
- Arduino Uno and a bunch of loose powder (resistors, conders, transistors, diodes).
What I want to do:
Using a small home-made arduino-based multimeter, take readings (voltage, current) from the solar panel throughout the daylight hours. Store the readings in the logs and transmit them to the server (as the transmitter, the Node MCU board, and in the role of the server, the raspberry), where the data will be plotted.
A huge request to you - a novice, that is, me, poke his nose into any subject literature on this issue. How to correctly implement all this.
If this algorithm is technically impossible to implement, are there any such ready-made tools?
