Indoor Houseplant Monitor Kit with ESP32 – Solar Powered Moisture Sensor

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 a plain plant stake into a self-sufficient soil guardian that never needs a battery swap. This kit lets you assemble a solar-powered ESP32-C3 device that reads soil moisture levels and broadcasts a wireless alert via BLE whenever your houseplant is parched—no cloud, no app subscriptions, just a simple beacon your phone can detect.

What You'll Build

You'll construct a sealed, plant-tag-sized monitor that fits into any pot. The included IP65 box houses the ESP32-C3 Super Mini, TP4056 charging module, and an 18650 cell, all fed by a 6V 1W solar panel. A moisture sensor probe measures conductivity in the soil, and the microcontroller sends a watering-needed notification over BLE to a nearby phone. Once built, the tag runs indefinitely on ambient light.

What You'll Learn

• Solder a complete PCB prototype from discrete components
• Program an ESP32-C3 to read analog sensor values and trigger BLE advertisements
• Design a solar charging circuit with battery protection
• Package electronics in a waterproof enclosure for real-world deployment

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Young learners aged 5-15 can build with a parent’s help, as the soldering is straightforward and the code is provided. It’s equally suited for CBSE Class 11-12 students working on IoT agriculture projects, B.Tech ECE/EEE undergraduates prototyping a low-power sensor node, or ATL Tinkering Lab facilitators introducing renewable energy and wireless communication. Even IIT/NIT/VIT/BITS teams at Smart India Hackathon can use this as a ready-to-deploy plant health demonstrator.

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.
