Arduino Monitor Solar Panel Voltage

The solar voltage monitor will stay connected to the test solar set up for a couple weeks.

Arduino monitor solar panel voltage.

Circuit diagram of arduino based digital voltmeter. If you decide to use a 5v arduino simply add a boost converter after the 3 3v supply amazon model xl6009 dc to dc converter. The 5v power supply module provides power to the microcontroller arduino wemos the current sensor acs712 and oled display. Therefor the analog signals must be adapted by a circuit to match with these specifications.

Since the adc of the microcontroller is coded in 10 bits the resolution of the pv panel module voltage is 0 00489 v 5 1023 and the input voltage of this module must be more than 0 02445 v 0 00489 v 5. Hence the output voltage of the pv panel can be formulated as the following equation. Power for the solar monitor is connected to the voltage out of the controller. In your design you can use nanoif you need the extra clock speed or possibly need to attach 5 v peripherals.

Once testing is complete and updated post will be made. Voltage analog value resistor factor reference voltage. Wire is installed to sample the battery and solar panel voltage. And suppose if you want to measure up to 10 volts then you have to use the given circuitry.

There is also a 5 volt arduino pro mini available that runs a 16 mhz clock. 230v ac 5v dc power supply module. The arduino analog input ports accept a maximum voltage of 5v.
