About LoRax

LoRax is an award-winning wildfire risk monitor. Specifically, LoRax is an IoT distributed system of nodes reporting information that is centralized via the cloud. The name comes from Long Range examination, from its ability to report soil moisture, temperature, UV light, humidity data, and GPS coordinates from nearly 300 meters away.

Mobile App

Hardware (Rock and Tree Node)

Rock Node

Tree Node

Software:

The progressive web app is built using a MongoDB/Express/React/NodeJS (MERN) stack using Heroku as our cloud server and MongoDB Atlas to store and persist data.

Hardware:

Each LoRax node uses an ESP 32, using the Arduino IDE to load and flash the firmware onto the board. Each node contains:

• UV sensor
• Temperature & humidity sensor
• Soil temperature & moisture sensor
• OLED display
• Neo-6M GPS
• 4 AA batteries (for power)

Each node communicates to our Heroku-hosted backend where data is
