Arduino Voltage Sensor Solar Panel

It is used to reduce the input voltage up to 5 times compared to the original voltage because the maximum analog input voltage of the arduino microcontroller is 5 v.

Arduino voltage sensor solar panel.

Pmax 300mw vmpp 4 5v impp 65ma so the solar panel s voltage 4 5v at max is a little higher than the arduino s 3 3v. 3 7v 18650 lithium ion battery 2000 mah or more 6v dc 500 ma solar panel breadboard. Supplying it at this high rate may damage the arduino so we must regulate our output. Circuit diagram of arduino based digital voltmeter.

And suppose if you want to measure up to 10 volts then you have to use the given circuitry. The sensor reading is a digital value vout which varies between 0 and 1023. Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. For measuring voltage we have to follow the given formula.

I plan as well to mount a light sensor next to the solar panels. Mcp1700 3302e 3 3v voltage regulator. Apart pv panel arduino uno board voltage and current sensor different components are used in the experimental setup such us lamps of 100 w that act as a solar simulator a variable resistance between 0 and 300 ω as a load and acting as a light intensity driving. The voltage sensor module will be installed in parallel with the pv panel load as shown in figure c.

For calculation of the power the voltage is measured as well with a voltage transformer. The light sensor will be connected with an i2c serial connection. 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. Selecting the right arduino for your project.

Listed here are the various attributes used to determine the best suited for our example. In this exercise we will compare the three different arduino boards to see which one best fits your needs. Jumper wires actual values will depend on your project s power requirements. Voltage analog value resistor factor reference voltage.

Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun. The sensor module along with arduino taking 100mah current.
