Lawn Irrigation Controller Kit v7
Arduino Lawn Irrigation Controller Kit v7 – Smart Watering That Saves Every Drop
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you build an automated lawn watering system that reads soil moisture and rain conditions to make smart irrigation decisions. It skips a scheduled watering cycle if recent rain has kept the soil wet, preventing waterlogging and conserving water. Ideal for Indian climates where monsoon downpours can follow dry weeks.
What You'll Build
A fully functional irrigation controller with an LCD display showing the current schedule, moisture levels, and rain status. The relay toggles a water pump or solenoid valve based on real-time sensor data, so your lawn stays green without manual intervention.
What You'll Learn
- Reading analog soil moisture sensors and calibrating thresholds for your soil type
- Interfacing a rain sensor and interpreting digital signals to avoid false triggers
- Using a DS3231 RTC module to create and run time-based watering schedules
- Controlling a 5V relay for pump switching with flyback diode protection

Who This Kit Is For
This kit is ideal for CBSE Class 11–12 students building agricultural automation projects, B.Tech ECE/EEE students working on IoT-based water management, and Smart India Hackathon teams prototyping sustainable solutions. It also fits ATL Tinkering Labs teaching sensor integration and environmental monitoring.
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 on the kit box to access the AI companion trained on this exact project. It offers step-by-step troubleshooting, and you can also reach us on WhatsApp for direct help.
Can this controller be connected to an actual water pump?
Yes, the 5V relay module can switch a 230V AC pump through its COM/NO terminals. The kit includes 1N4007 diodes for flyback protection. Always consult an electrician for high-voltage wiring safety.
How does the kit handle rain after a scheduled watering is due?
The rain sensor is continuously sampled. If rain is detected when a watering cycle would normally start, the controller skips that cycle entirely. This prevents soggy lawns and wasted water.
Can I add Wi‑Fi to monitor the system remotely?
The Arduino Uno doesn’t have built-in Wi‑Fi, but you can easily connect an ESP8266 or ESP32 module. The AI companion includes code snippets and wiring tips for adding remote monitoring.
Lawn — Soil moisture and rain sensor together control watering. Skips schedule if rain is detected.
