Arduino Monitor Solar Panel Voltage

Voltage analog value resistor factor reference voltage.

Arduino monitor solar panel voltage.

Wire is installed to sample the battery and solar panel voltage. 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. Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. Power for the solar monitor is connected to the voltage out of the controller.

And suppose if you want to measure up to 10 volts then you have to use the given circuitry. Circuit diagram of arduino based digital voltmeter. The 5v power supply module provides power to the microcontroller arduino wemos the current sensor acs712 and oled display. The arduino analog input ports accept a maximum voltage of 5v.

Once testing is complete and updated post will be made. For measuring voltage we have to follow the given formula. 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. Therefor the analog signals must be adapted by a circuit to match with these specifications.

In your design you can use nanoif you need the extra clock speed or possibly need to attach 5 v peripherals. 230v ac 5v dc power supply module. The ac current passing through the load is sensed by the current sensor module acs712 and fed to the analog pin a0 of the arduino wemos board.
