Navigation and Environmental Mapping Operations
An autonomous underwater sensor platform with a real-time oceanographic mission control dashboard. Built for SMATHHacks 2026.
NEMO is an IoT-enabled submarine that collects environmental data — temperature, turbidity, and pH — and streams it to an interactive web dashboard. The dashboard provides a 3D/2D globe visualization with scientific ocean color mapping, float tracking, and click-to-measure capabilities.
An ESP32 microcontroller reads from three sensors (DS18B20 temperature, analog turbidity, analog pH) and transmits JSON data over WiFi.
The submarine housing was designed in Onshape as a two-part shell enclosure.
A canvas-based oceanographic dashboard featuring an interactive 3D globe, multi-variable visualization (SST, turbidity, pH), autonomous float trajectory tracking, and a mission control HUD.
