Greenhouse Soil Manager Plus Kit with Arduino Uno + Sensor
Build Your Own Automatic Greenhouse Watering System with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a greenhouse where every plant gets exactly the water it needs — no more, no less. This kit lets you build an intelligent soil moisture controller that reads the moisture level, activates a pump for a precise 5-second burst when the soil is dry, and then waits until the soil truly needs water again. It's the secret to healthier plants and less wasted water.
What You'll Build
You'll assemble and program a working soil moisture monitoring system that autonomously waters plants. After a successful build, you'll see the Arduino read the sensor, light up the relay, and pump water through the silicone tube when the soil drops below your set threshold. The hysteresis logic means the pump won't turn on again until the moisture level recovers and drops a second time, preventing over-watering.
What You'll Learn
- Interfacing a soil moisture sensor with Arduino to read analog soil data
- Controlling a 5V relay module to drive a mini submersible pump safely
- Programming hysteresis in Arduino to avoid rapid pump cycling and root damage
- Using a breadboard for clean, modular circuit assembly and rapid prototyping

Who This Kit Is For
This kit is designed for students in CBSE-affiliated schools working on Arduino-based projects, young innovators at ATL Tinkering Labs, and first-year engineering students building practical sensor systems. It's also a great weekend STEM activity for parents and kids who want to understand automatic watering and hysteresis. The 5–15 age range makes it ideal for guided learning or a confident young maker’s first real-world automation.
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?
Our AI companion, accessible via QR code, walks you through every step, and our WhatsApp support is ready for extra help.
Can I use this kit outdoors in a real greenhouse?
Yes, the kit works on a breadboard for learning, but you can later transfer the circuit to a waterproof enclosure and use a larger pump. The logic remains the same.
How do I adjust the moisture threshold?
The Arduino code lets you set a threshold value; you can tweak it based on your soil type. The AI companion will guide you through modifying the code.
Is the pump strong enough to draw water from a tank?
The mini submersible pump can lift water up to 50cm; for larger setups, you can replace it with a higher-power pump, controlling it through the same relay module.
Greenhouse — Soil moisture below threshold triggers relay pump for 5 seconds. Hysteresis prevents over-watering.
