Lawn Irrigation Controller Mini Kit with Arduino Uno + Sensor
Arduino Lawn Irrigation Controller Kit — Build an Icon-Based Plant Health Score Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Your lawn talks in sensor data, not words. This kit transforms numbers into an icon-based plant health score on a full-colour TFT, so you know exactly when to water, shade, or warm your plants. It’s a complete closed-loop monitoring system built around Arduino Uno, combining three environmental sensors into one intuitive dashboard.
What You'll Build
By the end of this build, you’ll have a standalone device that monitors soil moisture, ambient light, and air temperature. The TFT screen shows a plant health bar, a sunlight icon, and a temperature gauge — all updating in real time. It’s a practical tool you can place on any lawn or garden bed to make irrigation decisions without guesswork. The entire system runs off a 9V battery, so you can deploy it away from a computer.
What You'll Learn
- Interface analog and digital sensors with Arduino
- Display custom icons and gauges on a colour TFT
- Transform raw sensor data into a composite plant health score
- Apply conditional logic to drive irrigation decisions

Who This Kit Is For
This kit is ideal for CBSE Class 11 and 12 students taking Computer Science or Informatics Practices, who need a data visualization project that reads real sensors. It’s a strong fit for ATL Tinkering Lab sessions on smart agriculture and IoT, as well as first-year B.Tech ECE students exploring sensor fusion. If you’re preparing for a Smart India Hackathon prototype or a school science exhibition, this kit delivers working output in a single afternoon.
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 to chat with the AI build companion, or send a WhatsApp message to our support team. You’ll get help specific to this exact kit, not generic forum advice.
Does this kit require soldering?
No, everything plugs into the included 400-point breadboard, so you can build and test without any permanent connections.
Can I use this kit outdoors on my lawn?
The sensors are not waterproof; place the unit in a sheltered spot or build a simple enclosure to protect it from rain while leaving the soil probe and sensor openings exposed.
How do I program the plant health score?
The AI build companion provides full Arduino code with clear comments. It combines moisture, light, and temperature into a score by comparing each reading against configurable thresholds, and you can adjust those easily to match your plant’s needs.
