COLIVERA

Overview

Developing Colivera, an IoT-based water quality monitoring system that integrates sensor nodes with LoRa, ESP-NOW, using LilyGoT3 and Mappi32 as a Master-Slave Architecture system and deliver the data to cloud.

Technical Details

• Architected a LoRa + ESP-NOW master-slave wireless network at 200m across 2 nodes (LilyGoT3 + MAPPI32), sustaining 4-hour continuous operation per charge cycle and delivering a 90% packet success rate.
• Designed custom PCB layouts via EasyEDA and fabricated enclosures in-house using 3D printing (Bambu Studio) and CNC, eliminating external fabrication dependencies and reducing prototyping costs.
