Air Quality Station with WiFi
This page describes setting up a simple air quality monitoring station. This was a prototype used in the development of our primary air quality monitor project.
- Arduino Uno
- K-30 CO2 sensor from co2meter.com
- Dust sensor (Shinyei Model PPD42NS)
- WiFi shield
- Grove shield
- DHT22 temperature and humidity sensor
- Wind speed sensor (optional)
- Grove cables
- Place the WiFi shield on the Arduino. Use jumpers on the shield to connect WIFI_TX to D7 and WIFI_RX to D6.
- Place the Grove shield on top of the WiFi shield.
- Solder a Grove cable onto the I2C lines of the CO2 sensor
- Connect the CO2 sensor to an I2C connector on the Grove shield.
- Connect the dust sensor to D3.
- Connect the temperature and humidity sensor to D4.
- If you are using a wind speed sensor, connect it to D2.
- Set up a data set patterned after the one provided below.
- Make a copy of the Arduino sketch and specify your data set ID, network name, and network password.
- Send the sketch to your Arduino.
Here is a data set from one of our test systems.
