One thing I completely missed while working on this project is that the Arduino Nano 33 IOT has an inbuilt temperature sensor which could be used to measure temperature in place of DHT 11. Actually, this sensor is only available under a beta edition of the library. I will work on this and try to incorporate it in the project in the future.

This project can be further improved in many ways. For irrigation, drip irrigation method can be employed. This will help reduce water consumption drastically. Drip irrigation pipes can be installed in the farm and the watering can be done using IOT and soil sensor.

Adding more soil sensors to irrigate the farm will make it much more efficient and appropriate for a large farm. This is certainly something that can be worked upon.

I had to remove my servo motor for Ultrasonic Sensor due to lack of space in my chassis. This can be added quite easily with a bigger chassis and make the bot more efficient.

The accuracy of LDR is not too great for measuring intensity. It could be replaced with a more reliable photo diode which would improve efficiency and make the results more accurate.

Other than that using the data collected over a season or so, further changes can be made to pesticide spraying techniques to make it even more efficient. Overall this project has a lot of future developments possible which I will try to do after this competition. Hopefully I will be able to post those as a separate blog on elements14 at a later date.

Overall, this was a very fun project and I absolutely loved working on it. I would like to thank Design For a Cause 2021 Team, Design For A Cause 2021, Phil Hutchinson's Blog, Pauline Chan's Blog, Arduino for this great opportunity and providing us with guidance and the kit.

Hope that everyone reading this blog enjoyed going through this journey with me. Will be back soon!
