Arduino Voltage Sensor Solar Panel

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.

Arduino voltage sensor solar panel.

I plan as well to mount a light sensor next to the solar panels. The sensor reading is a digital value vout which varies between 0 and 1023. Listed here are the various attributes used to determine the best suited for our example. 3 7v 18650 lithium ion battery 2000 mah or more 6v dc 500 ma solar panel breadboard.

Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun. One is measuring the current coming from the solar panels the second one is measuring the house main line current. 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. Voltage analog value resistor factor reference voltage.

For measuring voltage we have to follow the given formula. Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. In this exercise we will compare the three different arduino boards to see which one best fits your needs. Mcp1700 3302e 3 3v voltage regulator.

Jumper wires actual values will depend on your project s power requirements. For calculation of the power the voltage is measured as well with a voltage transformer. 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. Sensor used to measure snow depth sdi 12 rs 232 rs 485 snow depth 0 5 to 10 m 1 6 to 32 8 ft 45 to 50 c lws l surface wetness sensor dielectric sensor to determine presence of water and ice analog voltage dry frosted wet 250 mv to 1500 mv millivolt reading relates to moisture state 20 to 60 c cs135 lidar ceilometer.

Circuit diagram of arduino based digital voltmeter. Selecting the right arduino for your project. Supplying it at this high rate may damage the arduino so we must regulate our output. 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.

The voltage sensor module will be installed in parallel with the pv panel load as shown in figure c. 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.
