Solar Powered Smart Irrigation with IoT Variant 1
ESP32 Solar Smart Irrigation Kit: Automate Farming with IoT & Solar Power
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 farm into a connected, water-efficient operation with this solar-powered IoT irrigation system. Using an ESP32, three soil moisture sensors, and MQTT over WiFi, you’ll build a device that waters plants only when needed, conserves battery with deep sleep, and sends real-time data to your phone. Perfect for agricultural automation projects and smart farming innovations.
What You'll Build
You’ll assemble a weatherproof field unit that monitors soil moisture at three depths, detects rain, and controls dual submersible pumps. The system runs entirely on solar-charged 18650 batteries, waking from deep sleep only to check sensors and report via MQTT. An OLED displays local status, while your smartphone receives alerts and moisture trends.
What You'll Learn
- Design and program IoT systems with ESP32 and MQTT protocol
- Integrate solar charging, battery management, and deep sleep for off-grid operation
- Interface multiple sensors (soil moisture, DHT22, rain) and actuators (pumps) with precise control
- Build a weatherproof enclosure and manage power with buck converters and diodes

Who This Kit Is For
Agricultural engineers, B.Tech ECE/EEE students, and IoT enthusiasts building precision irrigation systems. Ideal for Smart India Hackathon teams tackling water conservation, off-grid sensor networks, and final-year projects at IITs, NITs, or VIT. Also a powerful hands-on tool for research labs testing sustainable farming solutions.
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 access the AI build companion with step-by-step guidance; you can also WhatsApp our support team for real-time help.
Can the system operate without WiFi?
Yes, the ESP32 can log data locally and control pumps based on pre-set thresholds using the OLED display, but MQTT reporting requires WiFi connectivity.
How long does the battery last on a single charge?
With the solar panel and deep sleep mode, the 2-cell 18650 pack can sustain the system for several cloudy days; sensor checks every 30 minutes keep power consumption minimal.
Is this kit suitable for a college agriculture IoT project?
Absolutely — it covers sensor integration, MQTT cloud communication, solar power management, and waterproofing, making it ideal for B.Tech final year projects or Smart India Hackathon submissions.
ESP32 + soil moisture + pump relays + WiFi MQTT. Solar charged. Deep sleep conserves battery.
