Shakthikulangara Project 2
Three science-fair projects, rewritten from scratch: firmware for every board, phone dashboards, a desktop robot-navigation app with a simulator and reinforcement learning, and the project reports.
| Project | Folder | Board | What it does |
|---|
| ⚡ Electronics: HazardGuard C3 | electronics/hazardguard_c3 | ESP32-C3 | LPG (MQ-5), alcohol/solvent vapour (MQ-3), overheating (DHT11) and water-leak (soil probe) alarm with green/yellow/red LEDs and a phone dashboard |
| 🐟 IoT: Marine Fish Quality Monitor | iot/fish_quality_monitor | NodeMCU ESP8266 | Watches a fishing boat's fish hold: ice temperature (DHT11), meltwater height and blocked drain outlet (ultrasonic), ammonia and methane from rotting fish (MQ-135, MQ-4). Logs the data, shows a summary on a TM1637 that flashes on faults, and gives the owner a phone dashboard, plus a laptop simulator. Wiring sheet |
| 🤖 Robotics: MarkerPilot | robotics | ESP32 car + ESP32-C3 gateway | Ceiling camera + ArUco markers drive a robot car to clicked points or goal markers; Kalman filter, classic + RL brains, simulator |
| 📄 Reports | reports | – | PDF reports for all three, rebuilt by python3 reports/build_reports.py |
Install the MarkerPilot app

install/INSTALL.md has the details, direct downloads and the pipx route.
Flash the boards
tools/flash.sh electronics # HazardGuard C3 (ESP32-C3)
tools/flash.sh iot # Fish Quality Monitor (NodeMCU ESP8266)
tools/flash.sh car # MarkerPilot car (ESP32-WROOM-32)
tools/flash.sh gateway # MarkerPilot USB gateway (ESP32-C3)
You need arduino-cli with the esp32 core 3.x, the esp8266 core 3.x (for the NodeMCU) and the libraries DHT sensor library (Adafruit) and TM1637 (Avishay Orpaz, IoT only). Add a port as the second argument if more than one board is plugged in.
Phones open the dashboard automatically when they join the hotspot.
