ESP32-C3 Smart Plant Tag Kit with ESP32 + Sensor
ESP32-C3 Smart Plant Tag Kit: Never Forget to Water a Plant Again
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a small tag nestled in your plant pot, reading soil moisture and silently signalling your phone when it’s time to water. This kit lets you build exactly that — a solar-powered, low-energy Bluetooth plant tag powered by the ESP32-C3, a tiny yet powerful microcontroller. Perfect for home gardeners, school science fairs, or anyone curious about smart farming.
What You'll Build
You’ll assemble a complete wireless plant monitoring tag that fits into a waterproof box. It checks soil moisture with the sensor, processes data on the ESP32-C3, and broadcasts a BLE advertisement containing a watering alert when the soil dries out. The device is entirely self-powered by a solar panel and rechargeable battery, so you can place it outdoors and forget about batteries.
What You'll Learn
- Solder and assemble a low-power electronic circuit
- Program an ESP32-C3 microcontroller to read analog sensor data and broadcast BLE advertisements
- Set up a solar charging circuit using the TP4056 module
- Debug and test a wireless sensor node for real-world use

Who This Kit Is For
This kit is ideal for young makers aged 10 and above exploring IoT and robotics, especially students in ATL Tinkering Labs or CBSE Class 7–10. It’s also a great parent–child project that introduces real-world electronics, soldering, and programming. B.Tech ECE/EEE students looking for a simple wireless sensor project will find it a perfect starting point.
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?
Our AI build companion, accessible via QR code, provides step-by-step guidance specific to this kit. If you need more help, reach out on WhatsApp for direct support.
Can I use this kit outdoors?
Yes, the IP65 plant tag box protects the circuit from splashes and dust, and the solar panel charges the battery for continuous outdoor operation.
Do I need prior programming experience?
No, the kit includes pre-written code that you can flash via USB. We’ll guide you through the simple setup, so even beginners can get it running.
How do I receive the watering alerts?
The ESP32-C3 broadcasts a BLE advertisement that can be picked up by a smartphone app like nRF Connect. You’ll learn how to decode the soil moisture level and set up a custom watering notification.
Solar powered ESP32-C3 in a plant tag reads soil moisture and BLE broadcasts watering need alert.
