Lawn Irrigation Controller Kit v6
Lawn Irrigation Controller Kit v6: Create an ESP32-Powered Plant Watering Alert System
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 child or student will wire a soil moisture sensor to an ESP32 board, program it to read moisture levels, and build a visual and wireless alert system. When the soil gets too dry, a red LED lights up and a notification pings your phone—teaching real-world IoT and automation. Perfect for a balcony tomato plant or a school science project that demonstrates embedded systems.
What You'll Build
By the end of this 2–3 hour project, you’ll have a working soil moisture monitor that flashes a green LED when the soil is damp, and a red LED with buzzer when it’s time to water. The ESP32 connects to your WiFi and sends a message to a companion app or web dashboard—no cloud subscription needed. It’s a standalone, battery-optional gadget you can place in any pot or garden bed.
What You'll Learn
- How to read an analog soil moisture sensor and interpret its output
- Connecting components on a breadboard and understanding resistor usage
- Uploading code to an ESP32 microcontroller using the Arduino IDE
- Configuring WiFi and sending basic HTTP notifications to your phone

Who This Kit Is For
Students in ATL Tinkering Labs and CBSE Class 11-12 working on embedded system mini-projects will love the guided, age-appropriate build. It’s also ideal for B.Tech ECE first-years exploring IoT, or for parent–child duos nurturing a kitchen garden with a tech twist. If you’ve participated in Smart India Hackathon junior editions or are setting up a science exhibition, this kit drops right in.
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?
The AI companion walks you through each step, and you can send photos over WhatsApp for live troubleshooting from our makers.
My plant is far from the WiFi router. Will it work?
The ESP32 has decent range, but for balconies or gardens 20-30 feet away it should connect. If not, the LED and buzzer still work offline.
Can I use this to automatically water the plant?
This kit focuses on alerts. To add a pump, you’d need a relay module (not included), but the build gives you the exact foundation.
Is coding experience required for a 9-year-old?
No—the AI companion provides pre-written code with explanations, and an adult can help upload it. Many 8-year-olds have built it with a parent’s guidance.
Lawn — Soil moisture below threshold triggers ESP32 to light LED and send WiFi notification to water the plant.
