ESP32 Solar Houseplant Monitor Kit - Self-Watering IoT System
Build a Solar-Powered Self-Watering Plant Monitor with ESP32 & MQTT
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your home into a smart greenhouse. This kit lets you build a solar-powered system that monitors soil moisture, temperature, and humidity for up to three plants, automatically watering them and sending data to your phone via MQTT. Perfect for busy plant lovers who travel often and want to keep their greens alive without daily maintenance.
What You'll Build
A fully autonomous indoor plant care system that checks soil moisture every hour, waters plants when dry, runs entirely on solar energy, and logs data wirelessly to your home MQTT server. You can monitor your plants from anywhere and never worry about over- or under-watering again.
What You'll Learn
- Circuit design with ESP32 deep sleep for ultra-low power
- MQTT protocol for IoT data logging and real-time monitoring
- Solar power management and battery charging circuits using TP4056 and LM2596
- Integrating multiple sensors and actuators with real-time feedback on an OLED display

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 companion provides instant debugging help, and you can send photos via WhatsApp to our team for personalized assistance.
Can I add more plants to this system?
Yes, the ESP32 can support up to 8 analog sensors; you can expand with additional moisture sensors and relays.
Does the kit work without sunlight?
The battery charges from the included solar panel, but you can also charge it via USB if sunlight is insufficient.
Is soldering experience required?
Yes, this kit requires intermediate soldering skills to assemble the prototype board and power circuit.
