Measure PM2.5 Concentration in the air with Ameba RTL8722DM

Ameba RTL8722DM is a low-power dual-band WLAN and BLE(Bluetooth Low Energy) SoC by Realtek. The RTL8722DM also include memory for Wi-Fi protocol functions and application making it simple for anyone to develop various kind of IoT applications. At the same time it has a wide range of peripheral interfaces. With all these interfaces, it can connect to most of the electronics components like LEDs, temperature and humidity sensors, and so on.

PMS3003/PMS5003 is a digital and universal particle of concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. For this project, the sensor output its data via UART. The PMS3003/PMS5003 detects the concentration value of PM2.5 which stands for the fine particle with a diameter of 2.5 micrometer or less.
