Arduino Voltage Sensor Solar Panel

Selecting the right arduino for your project.

Arduino voltage sensor solar panel.

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. Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer. Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun. And suppose if you want to measure up to 10 volts then you have to use the given circuitry.

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. For measuring voltage we have to follow the given formula. 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.

Supplying it at this high rate may damage the arduino so we must regulate our output. One is measuring the current coming from the solar panels the second one is measuring the house main line current. In this exercise we will compare the three different arduino boards to see which one best fits your needs. The sensor module along with arduino taking 100mah current.

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. Listed here are the various attributes used to determine the best suited for our example.

Jumper wires actual values will depend on your project s power requirements. The sensor reading is a digital value vout which varies between 0 and 1023. I plan as well to mount a light sensor next to the solar panels. 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.

The voltage sensor module will be installed in parallel with the pv panel load as shown in figure c. Voltage analog value resistor factor reference voltage.
