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 #Components used -Arduino UNO -LCD display(16*2) -Soil moisture sensor -vibration sensor -buzzer
