The RootNet-SmartPot is an ESP32-based modular sensing unit designed for intelligent indoor plant monitoring. It serves as the perception layer for the RootNet ecosystem, collecting environmental data and providing immediate local feedback.
Features
- Comprehensive Sensing — Monitors soil moisture, ambient light (Lux/RGB), temperature, and humidity.
- Local Feedback — Features an SSD1306 OLED display for real-time status updates (e.g., "Needs Water", "Too Cold", "OK") without network dependency.
- Power Efficiency — Optimized for long-term battery operation using ESP32 Deep Sleep cycles.
- Energy Harvesting — Supports autonomous operation via a 0.5W solar panel and an integrated LiPo charging circuit.
- Connectivity — Transmits telemetry via Wi-Fi to a central RootNet server for data logging and remote monitoring.
