Soil Moisture Detector

簡介: For my Arduino project, I wanted to make something meaningful that can actually help me solve the problems that I face in my life. I thought about the things I struggled with and the first thing that came in my mind is how I always forget to do things and one of those things is watering my plants. So I made a device that would automatically remind me to water my plants if/ when the soil gets too dry. This way the device would not only be a project for school but also can be really useful in my life too

I didn’t completely follow the tutorial, as you can see, the circuit and codes are different, I only used this website to get ideas and see the materials I needed. I added the alarm that would actually remind me to water the plant.

6.材料清單:

Materials needed for this project are:

1k resistors x1

LED light x1

10k piezo Buzzer x1

Soil moisture detector set x1

Assorted wires

Arduino Leonardo x1

Breadboardx1

CIRCUIT

Step 1 In case the picture wasn’t clear enough,

GND >> -

5v >> +

for the moisture sensor:

AO >> GND

DO >> A0

VCC+ >> +

For the buzzer:

+ >> pin 6~

- >> -

For the LED light:

Anode >> Resistor >> pin 7

Cathode >> -

PACKAGING

Step 1: find a box that fits the board

Step 2: Measure a hole on the top of the box to stick the sensor out

Step 3: cut out the hole

Step 4: find and measure a hole big enough to fit the USB cord

Step 5: cut out the hole

Step 6: also on the top of the box, cut a smaller hole to put the LED light through

Step 7: place the device in the box with the USB cords plugged in and seal the box

TESTING

Step 1: find some dried out soil

Step 2: place the sensor in the soil and check that the buzzer and LED lights work properly

Step 3: pour water in the soil and check if it properly detected the moisture and stopped the alarm

In the end despite all of the frustrating times where I would get stuck on a line of coding or when I had to start over because it did not work, I was pretty proud of the device that I made. It was not only useful, but I also learnt a lot on the way, I pushed myself to do more even when I didn't want to and I improved my computer skills a lot during the duration of this task.

The video of my device actually working is here:
