GeoWise
IoT climate control for polytunnels.
Problem
Polytunnel climate was adjusted by hand. Temperature, humidity, and irrigation needed to stay in range without someone on site.
What I built
- ESP32 sensor and actuator network over MQTT
- NestJS + RabbitMQ ingestion and command path
- Real-time dashboards for climate and device state
- Mobile access via Capacitor for remote control
Outcome
A working IoT loop: measure, decide, actuate, and watch it from a phone.
