Arduino Red Board Solar Panel Measurements

This project is a solar tracker with live data feed powered by the windows iot core running on the raspberry pi 2.

Arduino red board solar panel measurements.

Voltage is measured by the help of a voltage divider circuit as the arduino analog pin input voltage is restricted to 5v i designed the voltage divider in such a way that the output voltage from it should be less than 5v my battery used for storing the power from the solar panel is rated 6v 5 5ah so i have to step down this 6 5v to a voltage lower than 5v. The one used in this project is a 9 gram analogue servo. The specific servo model or size has not been stated as it depends on the size and weight of your solar panel. And suppose if you want to measure up to 10 volts then you have to use the given circuitry.

For measuring voltage we have to follow the given formula. The system uses non invasive ct sensors to measure the current. Installation node red platform. Arduino yun solar panel monitoring system.

The sensor module along with arduino taking 100mah current. No start search for arduino board in the local network yes start the main activity search for arduino board successfull. Measuring solar radiation with arduino. Battery voltage 1 2 x 2 2 4v so required voltage for solar panel 2 4 x 1 5 3 6v by taking some margin we can choose a 4v solar panel for it.

Battery capacity is 1300mah c 10 130mah the solar panel has to provide current 100mah for arduino along with a current not more than 130mah. Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. It is built up of 2 main parts. Emergency household lighting using power leds powered by the solar panel and lead acid battery.

At sun of 10 30am the maximum value of the solar panel is 21v although the characteristics indicate and guarantee 18v max without connected load it is normal that it generates 21v. Want to measure solar radiation but cant afford a pyranometers. Well make your own device with your arduino board using this guide. Aug 30 2015 solar powered led light circuit diagram and schematic design.

So we do not have to temper directly with the 240v or 110v lines. The raspberry pi running as the main controller and an arduino which takes care of moving the servos and taking the light measurements. Circuit diagram of arduino based digital voltmeter. Measuring dc voltage with arduino and node red.

You can use any size pwm hobby servo with the arduino although the larger servos will require their own power source.
