我通過(guò)設(shè)計(jì)具有更多功能的 PCB 升級(jí)了這個(gè)項(xiàng)目，您可以從這里檢查增強(qiáng)版:)

描述

我想通過(guò)使用光敏電阻產(chǎn)生的光強(qiáng)度值來(lái)近似評(píng)估太陽(yáng)能電池板在給定方向上產(chǎn)生的能量。太陽(yáng)能電池板在相對(duì)于光強(qiáng)度的高太陽(yáng)輻射下會(huì)產(chǎn)生大量能量，這就是為什么我打算使用光強(qiáng)度級(jí)別作為分配給 LED 顏色（紅色、黃色和綠色）的指標(biāo)。換句話說(shuō)，該項(xiàng)目用于預(yù)測(cè)太陽(yáng)能電池板在三個(gè)光強(qiáng)度閾值之間產(chǎn)生的能量，并在超過(guò)高閾值時(shí)通知您。

為了支持我的項(xiàng)目和文章，你可以在這里訪問(wèn)我的網(wǎng)站:)

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.
