My project is a brand new / emerging idea
Project Stage
Pilot-Stage (We’ve tried an activity or two)
Founding Story: What was the spark that led you to start your project? What was the "Aha!" moment that led you to get started and see the potential for this to succeed?
My interest in GreenFlow began when I was around 14 years old. I remember seeing my uncle's crops struggle under intense heat and dry conditions due to the changing climate. At the time, I did not fully understand the agricultural challenges behind it, but I remember wondering why something as essential as water could become such a difficult resource for farmers to manage. Years later, as I began studying Mechatronics Engineering, I started seeing everyday problems differently. I was learning how sensors, electronics, automation and renewable energy could be combined to solve practical challenges. That was my "aha!" moment. I began thinking about how these technologies could be applied to irrigation, particularly for smallholder farmers who may not have access to expensive or reliable systems. I started developing GreenFlow, a solar-powered smart irrigation system that uses soil-moisture sensors to help automate watering. What began as a childhood observation gradually became an engineering project and a commitment to solving a problem that affects people's livelihoods. I may not have all the answers yet, but I believe technology should make life easier for the people who need it most. That belief is what keeps me building GreenFlow.
The Problem: What problem are you helping to solve? Why does it matter to you and your community?
For smallholder farmers, a successful harvest can depend on something as basic as having enough water at the right time. Yet changing rainfall patterns, prolonged dry seasons and rising temperatures make it increasingly difficult to know when and how much to irrigate. When crops receive too little water, farmers risk losing their harvests, income and the resources invested in their farms. Although irrigation can help farmers manage these challenges, access remains difficult. Many smallholder farmers rely on manual watering or traditional methods, while more advanced irrigation systems may be too expensive, require reliable electricity or be difficult to maintain. This leaves farmers with limited options for managing water efficiently, especially in areas with inadequate infrastructure. This problem is personal to me. Growing up, I watched my uncle struggle to keep his crops alive under intense heat and dry conditions. That experience stayed with me and later inspired me to explore how engineering could help address the challenge. Through conversations with over 100 farmers, I have come to understand that the issue is not simply about introducing technology; it is about making useful technology affordable, reliable and suitable for the realities of farming communities. I want to help change that by making smarter irrigation more accessible to the farmers who need it most.
Your Solution: How are you solving this problem? Share your specific solution.
GreenFlow, developed by ASHBots Innovation Ltd., is a solar-powered, AI-enabled smart irrigation system designed to make efficient water management more accessible to smallholder farmers. The system uses capacitive soil-moisture sensors to monitor soil conditions. These readings are processed by an ESP32 microcontroller, which automatically controls a water pump through a relay. When the soil becomes too dry, irrigation is activated; once the required moisture level is reached, the pump switches off, helping prevent unnecessary watering. GreenFlow also incorporates weather data into its development roadmap, with the aim of combining soil-moisture readings with rainfall forecasts, temperature and other environmental conditions to support smarter irrigation decisions. We plan to use AI and data analysis to identify patterns, improve irrigation recommendations and help farmers make more informed decisions about when and how much to water. Solar energy and battery storage reduce dependence on unreliable grid electricity, making the system suitable for farms with limited access to power. We are developing GreenFlow to support multiple irrigation zones, remote sensor communication, water-flow and tank-level monitoring, and a simple dashboard for tracking system activity. Our approach combines practical engineering with farmer participation. Feedback from over 100 farmers is helping guide the development of a solution that responds to real agricultural needs. Our goal is to make intelligent, climate-responsive irrigation more affordable, reliable and accessible to smallholder farmers.
Impact: How has your project created impact / made a difference so far? Or, if at an early stage, what will impact look like?
GreenFlow is currently at the prototype development and validation stage. While we have not yet completed structured farm deployments or measured changes in crop yields and water savings, we have made meaningful progress in developing the technology and engaging the farmers it is intended to serve. So far, we have engaged over 100 farmers through conversations about their experiences with water scarcity, unpredictable weather, irrigation costs and access to agricultural technology. Their feedback has helped us understand practical challenges and shape our development priorities. We have also developed and tested a working prototype using soil-moisture sensors, an ESP32 microcontroller, automated pump control and solar power. GreenFlow has received recognition through the NASENI Innovate Naija Challenge, where I emerged as Niger State Champion, and the NextGen Innovation Challenge, where I showcased the project in London. The Air Force Institute of Technology, Kaduna, has also expressed willingness to support our work through workspace, mentorship and other institutional resources.Our next priority is to test GreenFlow on farms, monitor its performance and water usage, and gather farmers’ feedback to guide improvements and assess its potential to support more efficient, climate-resilient irrigation.
Your Innovation: What is different about your project compared to other programs or solutions already out there? How is your project new or innovative?
GreenFlow's innovation is not simply the use of solar power or soil-moisture sensors, as these technologies already exist. It lies in how we are combining and adapting them to address the practical realities of smallholder farmers, particularly those who are often overlooked by expensive or complex agricultural technologies. GreenFlow uses soil-moisture sensors to monitor actual field conditions rather than relying entirely on fixed watering schedules or manual observation. An ESP32 microcontroller processes the readings and automatically controls irrigation, while solar energy and battery storage reduce dependence on unreliable grid electricity. We are also developing plans to integrate weather data, including rainfall forecasts and temperature, with soil-moisture readings. By applying AI and data analysis to these combined inputs, future versions of GreenFlow could identify patterns and generate more informed irrigation recommendations, helping farmers decide when and how much to water. Our development roadmap also includes multiple irrigation zones, remote sensor communication, water-flow and tank-level monitoring, and a simple dashboard for tracking system activity. Another important part of our approach is farmer participation. Through engagement with over 100 farmers, we are learning about their needs and using their feedback to guide design decisions. We want to build a system that can be adapted to different farm conditions rather than assuming one design will work for everyone. Ultimately, our goal is to make smart irrigation practical, affordable and accessible by designing around farmers' realities, not expecting farmers to adapt to technology that was never designed with their needs in mind.

Your team: What role(s) do your team members play? How do you share leadership with them?
GreenFlow is led by a six-person team. I am the Founder and Hardware Lead, overseeing product direction and hardware development. Siddiqah leads Media and Communications, while Asiya handles research and information gathering. Oshan supervises hardware development, alongside two university supervisors who provide technical guidance and mentorship. We collaborate across our different roles, share ideas and use feedback to guide decisions as we develop GreenFlow.
What’s Next: What are the next steps you plan to take to grow or strengthen your project over the next year? If your project is still in the idea stage, describe the steps you will take over the next three months to launch or begin developing it.
Over the next year, our priority is to move GreenFlow from prototype development to real-world farm testing. We plan to strengthen the hardware, improve sensor communication and power management, integrate water-flow and tank-level monitoring, and develop a simple dashboard for monitoring irrigation activity. We intend to deploy pilot units on selected farms, working directly with farmers to test the system under real farming conditions, gather feedback and measure its reliability, water use and suitability for different crops. The findings will guide further improvements and help us develop a more affordable and scalable version. We also aim to strengthen our technical team, collaborate with agricultural experts and organisations, and explore partnerships that can support product development, field testing and eventual production. Our institution, the Air Force Institute of Technology, Kaduna, has recognised our work and expressed its willingness to support us with workspace, mentorship and other institutional resources. We intend to use this support to strengthen our engineering capacity and accelerate development. Our goal is to build a dependable solution that farmers can trust and that makes climate-resilient irrigation more accessible.
How do you encourage other people to join your project or learn about the problem you’re working on? If you have a new idea, tell us how you will do this in the future.
We encourage participation by starting with conversations and helping people understand why the problem matters. So far, we have engaged over 100 farmers, listening to their experiences with water scarcity, unpredictable weather, irrigation costs and access to technology. Their perspectives have helped us identify practical challenges and shape GreenFlow around the needs of the people it is intended to serve. We also share our work through innovation programmes, competitions, professional networks and conversations with young people interested in engineering, agriculture and climate action. Showcasing GreenFlow at platforms such as the NASENI Innovate Naija Challenge and the NextGen Innovation Challenge in London has helped us reach wider audiences and connect with people who share an interest in practical solutions. Within our team, we bring together different skills in hardware development, research, supervision and communications. We encourage collaboration by giving members responsibilities, sharing ideas and involving them in decisions that strengthen the project. With the recognition and support expressed by the Air Force Institute of Technology, Kaduna, we also hope to involve more students, technical mentors and researchers in developing GreenFlow.
