Landslide Early Warning Alert System

#Overview
A hardware-based early warning system that detects precursor signs of slope instability using real-time environmental sensing, with live status display and audible alerting.

#Today’s progress

• Finalized the firmware logic (sensor reading, risk classification, alert triggering)
• Designed the circuit connections for the physical build
• Next step: assembling and testing the physical model (to follow in a separate post)

#How it works

• Continuously reads two environmental indicators: soil moisture and ground vibration
• Classifies current risk into three tiers based on sensor thresholds:
  • ‘SAFE’ — normal conditions
  • ‘MODERATE’ — one sensor reading elevated
  • ‘DANGER’ — both readings cross critical thresholds
• Displays live status on a 16x2 LCD
• Triggers a buzzer alert when DANGER conditions are detected
