The main control board acts as the central processing hub. It collects data from environmental sensors (e.g., PM2.5, CO2, VOC, temperature, humidity), processes it using embedded algorithms, controls system functions like fan speed and indicator lights, manages power distribution, and enables wireless communication for real-time monitoring and alerts.
The board operates with a supply voltage of 9–36 V DC, with typical power consumption ≤5 W at 24 V DC. The processor clock speed ranges from 80–240 MHz, and flash memory is 512–2048 KB. These are reference ranges; confirm exact values with the manufacturer for your specific model.
The board supports UART, I2C, SPI, Wi-Fi, and BLE interfaces, providing multiple options for IoT connectivity. The specific interfaces available may vary by model, so verify with the supplier.
The operating temperature range is -20–60 °C (optional -40–85 °C), storage temperature is -40–85 °C, and relative humidity should be 10–90% non-condensing. The ingress protection rating is IP30–IP42 per IEC 60529, depending on enclosure design. Always check the manufacturer's specifications for your application.
