Introducing EcoPi
A Living Laboratory
A micro-scale terrarium powered by sensors, automation and Raspberry Pi
- exploring how technology supports tiny, self-contained ecosystems.
Micro-Ecosystem
A sealed terrarium that simulates a tiny natural environment.
Robotics
Automated control of various sensors and actuators.
Internet of Things (IoT)
Environmental data captured by a Raspberry Pi.
About
A personal project combining science, sustainability and modern automation.
EcoPi shows how accessible technology can maintain and support small, sealed ecosystems.
Controlled Micro-Environment
EcoPi maintains conditions inside a glass vessel, creating a predictable environment for plant growth.
Hands-On Discovery
Experimentation by adjusting variables, observing changes and learning how living systems respond.
Accessible Design
Intentionally simple, allowing exploration of ecosystem behaviour without specialised laboratory equipment.
EcoPi blends sensors, automation and data insight to maintain conditions with minimal manual input.
Live Monitoring
Sensors measure temperature, humidity, light levels and soil moisture in real time.
Automatic Response
Lighting, airflow and watering activate only when readings fall outside the desired range.
Data Led Insight
All sensor data is gathered for clear, ongoing visibility into the health and behaviour of the micro-ecosystem.
EcoPi demonstrates how robotics and IoT can support sustainable ideas on a micro-scale.
GreenTech Principles
Energy-efficient components, optional solar power and recycled materials keep resource use low.
Practical Learning
It provides a hands-on way to explore sensors, control systems and environmental regulation.
Beyond The Test Tube
The same ideas apply to smart gardens, automated greenhouses and even future closed-loop habitats.
Features
Internet of Things (IoT)
An IoT network of Raspberry Pi devices using MQTT and Node Red to monitor sensors and control actuators within a self-contained terrarium ecosystem.
Automated Regulation
Fans, lighting and hydration activate only when conditions drift, helping maintain a stable micro-environment with minimal intervention.
Smart Monitoring
Node-RED dashboards provide clear, live visualisation of temperature, humidity and system behaviour — accessible from any device.
Connectivity
Uses Wi-Fi to share ecosystem data remotely, allowing monitoring and control from a phone, tablet or desktop.
Modular System
Built as a flexible platform where sensors, actuators and automation features can be added or swapped as the project evolves.
Compact By Design
A complete smart-terrarium system engineered to fit inside a recycled glass bottle, combining efficiency with minimal environmental impact.

About Nick Hilton
Creator of EcoPi
EcoPi is a personal project that brings together my background in science and my interest in robotics, environmental systems and sustainable design.
It’s a space where I experiment, test ideas and explore how technology can support small, self-contained ecosystems.
Before retiring in 2020, I spent more than forty years in technical roles, developing skills in analytics, instrumentation and systems thinking.
I now apply those same principles to hands-on projects in my workshop — learning, building and exploring new possibilities.
I enjoy sharing progress and connecting with others who like to make things, experiment, or explore how small-scale technology can have big uses.
The Three Sisters Nature Reserve provides a rich supply of FREE hardscape, drainage pebbles and simple plants to fill the terrarium.
FAQ

Is EcoPi for sale or commercial use?
No. EcoPi is a personal hobby project, created for learning and experimentation.
Can EcoPi be expanded?
Yes - Its modular design allows new sensors, features and automation to be added over time.
Do you need programming experience to build something similar?
Basic knowledge helps, but simple versions can be created with beginner-friendly tools and guides.
What tools and materials are used?
Raspberry Pi, sensors, PLA 3D-printed parts, recycled components and low-power electronics.
