A discreet individual living in Hanoi.
Collect, analyze and share independant data on air quality in Hanoi. Ultimately, to provide smog alerts for sensitive people, and collect enough data to make a proper year-to-year analyzis.
aqiVN.org is using a Dylos DC1100 Pro Sensor connected to a Raspberry Pi, running Raspbian (Linux). Data from the sensor is gathered using a custom script and sent in real-time to our servers. Air quality data is then processed and displayed using a custom, tailored-made PHP/MySQL interface.
Dylos DC1100 Pro: $290; Raspberry PI: $60; Serial to USB cable: $15;
Dedicated UPS: $45; Total: $410.
Software development and tests: around 80 hours.
aqiVN.org is a personal non-profit project for public interest, independently and privately funded by its primary maintainer.
You might check out the Vietnam Center for Environment Monitoring for official data (used by aqiCn.org), and the U.S. Embassy Hanoi Air Quality Monitor for a daily indicator in a much more central/busy area (Lang Ha).
The following sources of information are currently wanted, to correct
historical data and improve the
accuracy of the air quality indicator:
- temperature/humidity/rain/wind in the Nhat Tan area (historical data since 11/2014 + real-time)
- any accurate and updated source of information on harvest times in north Vietnam
- indicators of economical activity (electricity usage, road use..)
