Air Quality Monitor (PM2.5) with Secure Cloud Connection

Detecting poor air quality is vital for protecting against harmful exposure. Air quality can be compromised due to Volatile Organic Compounds (VOCs) and tiny particulates in the air. ​With widespread HVAC systems, the industry and mass market require simple, precise, and secure ways to monitor and control air quality.

This design features an all-in-one air quality module that detects parameters such as PM2.5, RHT, TVOC, and eCO2. It displays readings on a TFT LCD and uses a Wi-Fi connection to send alerts to the cloud when readings exceed a specific threshold.

System Benefits:

• Simultaneous multi-sensor measurements of all relevant air quality parameters​ for comprehensive detection.
• Real-time cloud connectivity​ allows for air quality monitoring from anywhere, at any time.
• Strong security at the Wi-Fi and upper stack layers​ protects against unauthorized access and ensures data integrity.
• HMI interface using onboard TFT controller​ enables real-time data display and control, allowing users to assess air conditions and adjust accordingly.
