JALRAKSHAK
Rethinking flood management with IoT & automation
JalRakshak is an intelligent dam-monitoring system that replaces slow, manual oversight with real-time sensing, automated decision-making, and cloud-based supervision — making dam safety faster, smarter, and more reliable.
Why current dam management falls short
Most dams in vulnerable regions still rely on outdated, human-dependent processes that simply cannot keep up with sudden weather changes.
Delayed Manual Response
Operators must physically check water levels — response time often lags behind rising flood risk.
High Flood Risk
Heavy rainfall can overwhelm dams within hours, endangering downstream villages and infrastructure.
Lack of Real-Time Monitoring
No continuous data on water levels, temperature, or rainfall means authorities react instead of preventing.
No Automated Control
Gate operation depends entirely on human action — slow, error-prone, and unsafe in emergencies.
An end-to-end IoT pipeline for dam safety
JalRakshak combines sensing, edge processing, automated actuation, and cloud monitoring into one cohesive smart system.
Ultrasonic Sensor
Continuously measures water level inside the reservoir with millimeter precision.
Rain Sensor
Detects rainfall intensity in real time, enabling early warning before water rises.
DHT Sensor
Tracks temperature and humidity to model environmental conditions accurately.
Servo Motor
Mechanically opens and closes the dam spillway gate based on water level thresholds.
Adafruit IO Dashboard
Visualizes all sensor data and exposes remote gate control from anywhere on the internet.
Quarky Controller
The brain of the system — reads sensors, runs logic, and drives both alerts and the servo gate.
What makes JalRakshak smart
Eight integrated capabilities that work together to deliver reliable, automated flood management.
Real-Time Monitoring
Live readings of water level, temperature, humidity, and rainfall.
Automatic Gate Control
Servo-driven spillway opens itself once thresholds are crossed.
Smart Alerts
Instant warnings to operators when conditions become critical.
IoT Cloud Monitoring
All data streams live to the Adafruit IO dashboard.
Remote Access
Authorities can supervise and operate the dam from anywhere.
Solar-Powered
Designed to run sustainably on solar energy at remote sites.
Low-Cost Solution
Affordable components make it scalable across many dams.
Flood Prevention
Acts before flooding starts — not after damage occurs.
From data to decision in seconds
A six-stage automated workflow that runs continuously without human intervention.
Data Collection
Sensors continuously stream raw readings of water level, temperature, humidity, and rainfall.
Sensor Processing
The Quarky Controller reads, filters, and converts the signals into actionable metrics.
Flood Detection
If thresholds are exceeded, the logic flags a potential flood condition.
Alert Generation
Audio-visual indicators and cloud notifications fire immediately to all stakeholders.
Automatic Gate Opening
The servo motor rotates the spillway gate to release excess water safely.
Cloud Monitoring
Every action and reading is logged to the IoT dashboard for transparent supervision.
