ESP32 Real-Time Alert Display
Embedded IoT Hardware Alert Monitor & Touch UI
Embedded IoT hardware display built with ESP32-S3 and LVGL that displays real-time missile alert telemetry and regional risk status before entering the shower during wartime.
TECHNOLOGY STACK & ARCHITECTURAL RUNTIME
Architectural Dossier
ESP32 Real-Time Alert Display (LinkedIn Demonstration) is an embedded IoT hardware and user interface experiment engineered to solve a visceral, real-world wartime dilemma in Israel: knowing if it is safe to enter the shower without missing a rocket siren.
The Problem
During periods of active rocket fire, standard smartphone notifications can be delayed, muffled by running water, or physically distant. Entering the shower creates an acute blind spot where auditory sirens may be masked. Dmitry engineered a dedicated physical telemetry console stationed directly outside the bathroom to provide instant, at-a-glance situational awareness.
Hardware & Implementation Details
- Microcontroller & Compute:
- Powered by an ESP32-S3 dual-core Xtensa LX7 processor running at 240 MHz with onboard Wi-Fi and Bluetooth LE.
- Display & Interface:
- Paired with a high-definition 480×480 display, delivering high contrast visual telemetry.
- Embedded Graphics:
- UI constructed using LVGL (Light and Versatile Graphics Library), an open-source embedded GUI library written in C/C++, providing hardware-accelerated animations, responsive widgets, and clear status iconography.
- Network & Telemetry:
- Continuously monitors active alert telemetry via Wi-Fi, rendering regional alert states, countdowns, and danger zone indicators with near-zero latency.
The experiment exemplifies Dmitry’s hands-on approach to engineering: identifying an immediate personal or physical challenge and rapidly prototyping an integrated hardware-software solution to solve it.
