Pollution Parameter Display Board

An IoT-enabled air quality monitoring and display system for Pollution Control Boards. Measures critical air quality parameters, displays real-time data on large P10 LED boards, stores data locally, and transmits securely to cloud servers with remote configuration support.

• Real-time AQI calculation using PM2.5 and PM10 data
• Large P10 LED display in multiple sizes
• Wi-Fi with Access Point mode for easy configuration
• SNTP time synchronization
• Secure MQTT data upload
• Local data storage (Mass Storage Class)
• Two-way remote control
• OTA firmware updates
• Configurable threshold alerts

Air pollution monitoring and public awareness require a reliable, real-time, and connected air quality monitoring and display solution. Manual data collection and isolated weather stations don't provide centralized access or real-time visibility.

Oxymora designed a Pollution Parameter Display Board based on the ESP32-S3 controller with environmental sensors and large-format LED display panels. The system is Wi-Fi enabled and supports secure cloud communication, OTA firmware updates, and local data storage.

• ESP32-S3 microcontroller
• P10 LED Display Panels (Single/RGB)
• PM2.5 and PM10 particulate sensors
• Gas sensor
• Temperature and humidity sensor
• RTC module
• Relay for display control

• ESP-IDF / Arduino framework
• MQTT (secure)
• SNTP
• Wi-Fi AP mode
• OTA updates
• Mass Storage Class (MSC)
• Cloud dashboard

Comprehensive, scalable, and future-ready solution for air quality monitoring. Enables effective public awareness while minimizing operational effort. Supports remote configuration and OTA updates.
