An Early Detection IOT Device for Heat Stroke Risk on Construction Workers

Early Detection IoT Device for Heat Stroke Risk Prevention

heatshield is an IoT smartwatch early detection system monitoring body temperature, pulse rate, ambient heat, and humidity to detect and prevent heat stroke risks among outdoor construction workers in high-temperature Philippine job sites.

Why Manual Safety Measures Fall Short

In tropical countries like the Philippines, construction workers engage in heavy physical labor under extreme direct heat. Body temperature rising above 40°C causes severe heat stroke, organ damage, or fatal incidents if left untreated.

heatshield eliminates manual monitoring limitations by combining smartwatch IoT physiological sensing (body temperature and heart rate) with site environmental monitoring (ambient temperature and humidity) to deliver early automated warnings.

High Environmental Heat

WBGT over 28°C and ambient heat above 35°C severely compromise construction worker physical endurance.

Silent Heat Stroke Buildup

Cardiovascular exertion and dehydration build up silently during heavy labor before symptoms appear.

Multi-Modal Safety Alerts

Redundant 4-channel alert system: wrist haptic vibration (for noisy sites), smartwatch audible buzzer, visual UI screen warnings, and automated supervisor cloud sirens.

The Three Platforms of heatshield

Designed specifically for construction firms to seamlessly connect field workers, mobile companions, and site management.

IOT SMARTWATCH DEVICE

Smartwatch Application

Primary end-user interface worn on the construction worker's wrist. Monitors skin temperature, pulse rate, ambient heat, and humidity in real time, triggering multi-modal warnings (haptic vibration, audible buzzer, and visual screen alerts) when thresholds are met.

MOBILE COMPANION

Worker Mobile App

Enables construction workers to view personal heat stroke risk trends, receive AI-driven hydration guidelines, and trigger emergency notifications.

SUPERVISOR DASHBOARD

Supervisor Command Center

Centralized cloud dashboard enabling construction site managers to oversee site-wide environmental heat levels and worker health data in real time.

Safety Escalation Risk Tiers Background
SIMULTANEOUS DUAL-LOGIC EVALUATION

Four Tiers of Heat Stress Prevention

Evaluates physiological vitals and environmental heat parameters simultaneously to filter false alarms and escalate safety interventions for construction crews.

TIER GREEN

Optimal Working State

Normal ambient and vital parameters. Worker conditions monitored continuously with quiet background telemetry.

TIER YELLOW

Hydration Advisory

Mild thermal accumulation. Smartwatch triggers gentle haptic wrist pulse and visual on-screen hydration icon.

TIER ORANGE

Mandatory Shaded Rest

Elevated heat stress. Watch triggers pattern haptic vibration, audible buzzer, and supervisor dashboard alert recommending shaded rest.

TIER RED

Emergency Intervention

Critical heat stroke threshold reached. Continuous haptic vibration, smartwatch buzzer siren, web audio alarm, and automated push notification evacuation signal.
