Arduino Voltage Sensor Solar Panel

3 7v 18650 lithium ion battery 2000 mah or more 6v dc 500 ma solar panel breadboard.

Arduino voltage sensor solar panel.

Supplying it at this high rate may damage the arduino so we must regulate our output. Listed here are the various attributes used to determine the best suited for our example. The voltage sensor module will be installed in parallel with the pv panel load as shown in figure c. One is measuring the current coming from the solar panels the second one is measuring the house main line current.

Circuit diagram of arduino based digital voltmeter. 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. The sensor reading is a digital value vout which varies between 0 and 1023.

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 sensor module along with arduino taking 100mah current. 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.

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. For measuring voltage we have to follow the given formula. Selecting the right arduino for your project. 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.

Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. Jumper wires actual values will depend on your project s power requirements. In this exercise we will compare the three different arduino boards to see which one best fits your needs. And suppose if you want to measure up to 10 volts then you have to use the given circuitry.

For calculation of the power the voltage is measured as well with a voltage transformer. I plan as well to mount a light sensor next to the solar panels.
