# Air Quality Monitoring Station

A web-based air quality monitoring station firmware. You can see the visualized real-time air quality data with the [Air Quality Widget][air-quality-widget], like the below image, or you can check the [raw data with a MQTT client][check-data-with-mqtt-client].



  



## How-to

### Setup Air Quality Monitoring Station & Check Data

We use [NodeMcu][node-mcu] (Arduino-like board with ESP8266 Wi-Fi chip) and [PMS3003 air quality sensor][pms3003] here. Please have them before you setup.

![Device](./images/device.jpg)

Let start to setup with the following steps.

1. Update the [SSID][ssid], [Wi-Fi password][password], and [MQTT topic][topic] (you can name it with any name you want) in the firmware, and flash the firmware with Arduino IDE.

  - Please ensure unplug the air quality sensor from the board when you do flashing. Because TX and RX will be used when do flashing.

2. Go to the [Air Quality Widget demonstration page][air-quality-widget-demonstration-page] to see the visualized data.

### Check Data With MQTT Client

Go to the [HiveMQ MQTT client web page][mqtt-client] and subscribe the [topic][topic] you assigned in the firmware.
