I will design smart esp32 sensor dashboards and automation nodes

Are you looking for a robust, production-ready IoT edge node or industrial monitoring system? Look no further! I am an experienced IoT & Embedded Systems Engineer specializing in microcontroller programming, precision sensor integration, and local human-machine interfaces (HMI).

Whether you need a smart factory safety monitor, an automated environmental control node, or custom C/C++ firmware, I will deliver clean, well-documented, and fully tested code tailored to your exact hardware.

Microcontroller Core: Optimized ESP32 firmware utilizing dual-core processing and low-level peripheral management.

Multi-Sensor Telemetry: Accurate data acquisition using digital sensors (BME280 for Temp/Humidity/Pressure) and analog air-quality detectors (MQ-135 with scaled 0100 index mapping).

Local OLED HUD Dashboard: Real-time visual diagnostics rendered directly on an SSD1306 OLED screen with zero cloud latency.

Autonomous Edge Actuation: Active-LOW opto-isolated relay control paired with piezo warning sirens for instant local hazard countermeasures.

Clean Code & Schematics: Fully commented Arduino/ESP-IDF C code, breadboard wiring guides, and hardware pin mappings.
