HydroGuard

HydroGuard is a real-time flood risk monitoring and alert system developed by The Fellowship of the Code. The system leverages IoT sensor technology, LoRa data transmission, a fullstack backend, and a user-friendly frontend interface to help municipalities monitor water levels and prevent flooding disasters.

Overview

HydroGuard gathers data from various environmental sensors, including:

• Pressure sensor (TL-136)
• Ultrasound distance sensor (HC-SR04)
• Soil moisture sensor (YL-69)
• Temperature and humidity sensor (DHT11)

Collected sensor data is sent using two Heltec LoRa 32 V3 development boards. The boards communicate using LoRa and then sends collected data using WiFi to our backend.
