Greenhouse Soil Manager Kit v5
Greenhouse Soil Manager Kit v5 — Build a Smart Irrigation System with Raspberry Pi Pico W
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your greenhouse into a self-regulating ecosystem. When the soil moisture drops below a set threshold, this kit’s Raspberry Pi Pico W activates a mini pump to irrigate plants. Every irrigation event gets logged via MQTT, giving you a real-time data trail accessible from any device. It’s a complete, practical lesson in IoT-enabled agriculture.
What You'll Build
You’ll assemble a soil monitoring station that reads dual moisture sensors, displays live readings on an OLED screen, and autonomously triggers a pump relay when the soil is too dry. The Pico W’s Wi‑Fi capability pushes event logs to an MQTT broker, so you can track watering patterns remotely. By the end, you’ll have a working smart irrigation prototype that could monitor a real planter box or greenhouse bench.
What You'll Learn
- Calibrate and read analog soil moisture sensors with the Pico W’s ADC
- Program relay‑driven pump control with threshold‑based logic
- Set up an MQTT client on the Pico W and publish structured IoT messages
- Display real‑time sensor data on a 0.96‑inch OLED using I2C

Who This Kit Is For
This kit is built for CBSE Class 11–12 students tackling IoT or agriculture‑themed coursework, first‑year B.Tech ECE/EEE learners exploring embedded systems, and Smart India Hackathon teams prototyping sensor‑driven solutions. It’s equally at home in ATL Tinkering Labs or a hobbyist’s weekend workshop.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code in the box to chat with our AI companion that knows every connection, resistor value, and troubleshooting step. You can also message us on WhatsApp — a real Compoden engineer will help within a few hours.
Can I view irrigation logs from my phone?
Yes. The Pico W publishes MQTT messages each time the pump runs. Using any free MQTT dashboard app (like MQTT Dashboard or IoT MQTT Panel), you can subscribe to the topic and see a live log of all events on your phone.
What if the pump runs dry or fails?
The included 1N4007 diodes protect the Pico W from back‑EMF spikes when the relay switches off. The kit uses a submersible pump designed for intermittent operation; the code can also limit pump runtime to prevent overheating.
Can I extend this kit for a full greenhouse?
Absolutely. The system uses breadboard‑friendly components, so you can add more moisture sensors, a water level indicator, or even a light sensor. The MQTT architecture scales easily to multiple zones.
Greenhouse — Soil moisture below threshold triggers relay pump. Pico W posts irrigation events to MQTT log.
