ESP32-S3 Smart Soil Moisture Predictor Kit: Predict Tomorrow’s Watering Need Today

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Harvest real soil moisture and temperature data every hour, then let the ESP32-S3 run an on-device linear regression that tells you whether your plants need water tomorrow. This kit takes you beyond static sensor readings into predictive analytics — you’ll build a mini weather station for your soil and see how edge AI can replace guesswork with data.

What You’ll Build

A self-contained prediction system that logs readings from two soil moisture probes and a waterproof DS18B20 temperature sensor. Every hour, fresh data feeds an algorithm that forecasts the next day’s moisture level and displays a clear “Water” or “Skip” recommendation on the 0.96-inch OLED. You’ll wire the entire circuit on a breadboard, upload the code, and watch the model adapt to your soil’s drying curve.

What You’ll Learn

• Sampling soil moisture and temperature with calibrated sensors and reading them over I²C and one-wire interfaces
• Storing hour-by-hour data on the ESP32-S3 to build a training set for on-device machine learning
• Implementing simple linear regression from scratch to predict next-day moisture based on recent trends
• Displaying real-time predictions, sensor status, and confidence metrics on an OLED screen

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students exploring real-world data science, first-year BTech ECE/EEE learners preparing for Smart India Hackathon, and ATL Tinkering Lab teams prototyping smart agriculture. If you’ve ever wanted to move from blinking an LED to training a tiny machine learning model on actual sensor streams, this kit bridges that gap in a single afternoon — no separate statistics course required.

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.
