Title: Industrial IoT Environmental Monitor, OLED HUD & Actuator Node
Description:
An autonomous edge-computing IIoT monitoring and safety node built using an ESP32 microcontroller. The system tracks real-time environmental metrics and executes local automation logic with zero cloud latency.
Key features:
1. Multi-Sensor Telemetry: Integrates a BME280 sensor for ambient temperature, humidity, and barometric pressure alongside an MQ-135 sensor for real-time air quality and gas detection.
2. Local OLED HUD Dashboard: Features an SSD1306 OLED display to provide operators with crystal-clear, on-site visual diagnostics and live system status updates.
3. Autonomous Edge Actuation: Automatically triggers an opto-isolated relay (M281) and piezo buzzer to drive ventilation fans and warning alarms when safety thresholds are breached.
4. Optimized Firmware: Powered by clean C/Arduino code utilizing hardware I2C communication, analog data mapping, and robust Active-LOW relay control logic.
