Smarter Gardening with Raspberry Pi + Arduino + NanPy

A quick project i've been working on to water my plants in my apartment. See blog.benreichert.com for more info.

This article is a summary of a YouTube video "Smarter Gardening with Raspberry Pi + Arduino + NanPy" by Blossom Flower Delivery

Key insights about video Smarter Gardening with Raspberry Pi + Arduino + NanPy

🌱 Automating the watering of plants with Arduino involves using a motor pump controlled by a transistor and a homemade hydrometer to measure soil resistance.

🌱 Drip irrigation is utilized in this setup, with a valve to adjust flow rates and a submersible pump to water the plants.

🌱 The Arduino is connected to a Raspberry Pi, which allows for higher level control and networking capabilities.

🌱 Python libraries, such as NAND pie, are used to communicate between the Arduino and Raspberry Pi.

🌱 The code for this setup is relatively simple, checking soil moisture levels and watering the plants if necessary.

🌱 The system includes error checking and ensures that the watering process does not occur too frequently.

🌱 This setup can be expanded upon to create a more complex automated watering system.

Timestamped Summary

00:01 The video is about automating watering of plants using an Arduino and Raspberry Pi.

00:08 The Arduino is connected to a breadboard and controls a motor pump using a transistor.

00:20 The Arduino also reads analog input from a homemade hydrometer to determine the resistance of the soil.

00:39 Drip irrigation is used to water the plant based on the water level detected by the hydrometer.

01:08 The Raspberry Pi is used to control the system at a higher level and perform networking and statistics.

01:25 The Raspberry Pi communicates with the Arduino over USB using a Python library called "nanpy".

01:44 The code for the project will be shared on GitHub.

01:56 The code checks the soil moisture level and waters the plant if necessary.

02:25 The system is running and the pump is watering the plant.

03:02 The code checks the soil moisture level every 2 seconds and prints values if the threshold is met.

03:26 The project is a simple implementation and might be expanded in the future.

Q&A

What is this project about?

This project is about automating the watering of plants using an Arduino and Raspberry Pi.

How does it work?

The Arduino reads the analog input from copper plates that measure the resistance of the soil to determine the water level. Based on this information, it controls a motor pump to water the plant. The Raspberry Pi is used to control the Arduino and gather statistics.

What components are used in this project?

The components used in this project include an Arduino, a breadboard, a motor pump, a transistor, copper plates, a drip irrigation system, a cycle valve, and a submersible pump.

Can I build this project with just an Arduino?

Yes, you can build this project with just an Arduino. However, the Raspberry Pi was used to enhance the control and networking capabilities.

Where can I find the code for this project?

The code for this project will be available on GitHub at some point.
