ESP32 Smart Garden Watering Kit - Predict Tomorrow's Watering Needs with On-Device AI

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

With this kit, you'll build a system that keeps your garden thriving without guesswork. Two soil moisture sensors and a temperature probe feed hourly data to an ESP32-S3, which runs a linear regression model on-device to forecast whether you'll need to water tomorrow. By the end, you'll have a working environmental monitor that learns from patterns and displays clear predictions on a crisp OLED-no cloud required.

What You'll Build

A smart garden watering assistant that samples soil moisture and temperature every hour, stores the day's readings, and at sunset runs a regression analysis to tell you if watering is needed the next morning. The OLED screen shows current sensor values, a 24-hour trend, and a plain-language "Water Tomorrow" or "Skip Tomorrow" message. Everything runs locally on the ESP32-S3 for reliable, offline operation.

What You'll Learn

• How to program the ESP32-S3 in Arduino IDE to read analog soil moisture sensors and the DS18B20 digital temperature probe
• How soil moisture and temperature correlate with plant water needs-and how to implement a linear regression predictor in C++
• Displaying real-time sensor data and prediction outputs on a 0.96-inch OLED using the Adafruit SSD1306 library
• Assembling a noise-free circuit on a breadboard with proper pull-up resistors, decoupling capacitors, and wire management

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you're a CBSE Class 11 or 12 student exploring IoT for a physics or computer science project, this kit gives you a working model with real-world environmental relevance. BTech ECE first-year students gain hands-on experience with sensors, microcontrollers, and basic machine learning that maps directly to lab curricula. ATL Tinkering Lab members can use this as a foundation for Smart India Hackathon challenges around agriculture or water conservation at IIT, NIT, VIT, or BITS Pilani.

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.
