我通過設計具有更多功能的 PCB 升級了這個項目，您可以從這里檢查增強版:)

描述

我想通過使用光敏電阻產生的光強度值來近似評估太陽能電池板在給定方向上產生的能量。太陽能電池板在相對于光強度的高太陽輻射下會產生大量能量，這就是為什么我打算使用光強度級別作為分配給 LED 顏色（紅色、黃色和綠色）的指標。換句話說，該項目用于預測太陽能電池板在三個光強度閾值之間產生的能量，并在超過高閾值時通知您。

How to calculate the generated energy by a solar panel

[ E = A * r * H * PR ] is the formula for calculating the generated energy by a solar panel, where A is the area of the solar panel, r is the efficiency, H is the average solar radiation and PR is the performance ratio or coefficient( usually 0.75).

You can change all solar panel values at the code below.

Connections

You can find a detailed connections guide at the code below.

?

?

?

?

1 / 2

?

Connect LED, photopesistor and GND wire to a mini breadboard. And, connect buzzer to control_1 mini breadboard.

?

?

?

?

?

1 / 2

?

Make the connections between all mini breadboards, and it is ready to detect light intensity.

?

?

?

?

Define threshold values to get accurate data

Energy production thresholds has three level at which LED colors change:

Low - Red

Moderate - Yellow

High - Green

?

?

Also, if you want, get the output through serial ports.

?

?

Now, you can use it to charge your Li-Po battery properly via a solar panel.
