Arduino - Remote Watering System (RWS)

This remote watering system was part of a final project that was to build a prototype by using an arduino. The project was done by three team members Hemachandra Dewamuni (Developer), Emmanuel (Research and Design) and myself (Design and Prototype). The task was to come up with an idea that would 1. Solve a Problem 2. Be empathetic 3. Have human interaction 4. Produce a prototype in less than a month.

We came up with an idea of creating a remote watering system that would help children with autism to interact and develop a love for gardening or taking care of plants in a fun way. We tried to create a prototype that was built with a number of household items so as to be economical and something a parent can put together for their special child.

Prototype assembly

On the server side, Arduino was run on Node with two libraries namely Johnny-5 and Narf.

First Prototype Design

The first prototype was the moisture placed in the plant and a water trough with a flap to open and close to water it. The problem with this prototype was the child would only be able to take care of one plant.

Final Prototype Design

This prototype is accomodating two plants, but can accomodate more depending on the number of plants the user has. In this design the trough is at the bottom and the pots have holes at the bottom getting the necessary amount from below. Furthermore depending on the amount the plant needs the water it can be raised from the bottom. The moisture amount is accounted by amount of water in the trough.

Making it friendly

To make this usage to the end user in our case the special child we had to develop the interface so as to make it interactive and friendly to the child. We came up with an idea to create a matching card game. In order for the child to be able to water the plants all cards needed to display a watering can. Due to constricting timeline, we used a timer sequence to run the interface as seen in the working prototype video

The Best Part

This project was awarded the best project during Humber Vanguard Grad show in April 2015
