设置变量

Wia 接收到数据后，必须对其进行处理，如果数据在最小值和最大值之间，则该值是安全的，pH 和水位传感器的限值已设置，但用户必须手动设置光敏电阻的限制，必须进行测试以确定此值，以下步骤将指导您如何执行此操作。

void setup(){ pinMode(1, OUTPUT); Serial.begin(9600); while(!Serial) {}; digitalWrite(1, HIGH);} void loop(){ const int val =analogRead(A3); Serial.println(val);延迟（5000）；} 

用户必须设置另一个变量，proDebug , 如果启用，Arduino 需要通过 USB 连接到计算机，并且必须打开 Serial Monitor，该模式下 Arduino 打印到 Serial Monitor，非常适合故障排除。 proDebug 默认为 false 用于现场操作。

决赛

最后一步是将您的Arduino连接到PC/Mac并上传草图，确保电池盒连接到Arduino并且电路正常。接下来的步骤将指导您为项目制作围栏。

我决定用一瓶水制作我的围栏，我认为这是一种很好的生态方式来拥抱这个项目。设备如下图所示。

如果您喜欢围栏的想法，您可以滚动浏览下面的图片，说明围栏是如何制作的，您可以自己制作。

The last thing to do is place the device in the river. To do this, go to the river you wish to implement MyRiver on during High Tide , this is essential to ensure that the device is not alerting that the river is flooding when it is actually just the tide.

Place some tape on the top of the water bottle to prevent water from seeping into the bottle and destroying everything.

We went to a local, dirty river to test the project out, all the alarms went off correctly.

When placing the probe in the water, ensure that the water is at the bottom of the water level sensor but is covering the photoresistor entirely. Secure the project to the shore using tape or a hammer and screws, and it should look like this (or better).

Background

Relaxing in your house, looking out the window at the once beautiful and delightful river rushing in front of you. But instead of the beautiful fresh river, you see a green slimy one, you might want to move house in that case.

And if the river decides to flood into your house in the middle of the night while you are sleeping, you will certainly decide to move.

I thought of these problems and how to solve them all in one device, and I came up with MyRiver.

If you are in the city and living beside a river, it will warn you in time if the river decides to ruin your day in any way or if your neighbour is dumping oil in the river. Or if you are on a farm, MyRiver will warn you that the river is dirty before you give the water to your animals, and will give you time to bring the animals in before the river floods.

But just reading the pH of the river was not enough, as insoluble substances like mercury or other metals do not effect the Ph of the water. So we came up with a new method to detect those substances, unique to this project, a photoresistor reading the amount of light from an LED penetrating the water. This way any water impurity can be detected.
