Mapping urban real-time pollution monitoring

The problem:

  • The people are not able to monitor environmental pollution in the city directly.
  • There is not sufficient, objective information for monitoring of environmental pollution and tackling violations.
  • Adjustment of planning in accordance with the current level of pollution is not effective.

Objectives:

  • Making a map of real-time urban pollution monitoring in some locations in Tay Ninh city using IoT.
  • Developing a STEM training program with a project-based approach for secondary school students, in collaboration with Fab Lab.

This map is to describe a monitored area within 2km from Tay Ninh city centre.

Types of pollution:

  • Noise caused by: vehicles, construction works, activities of people.
  • Light intensity at night
  • UV rays
  • Temperature and humidity
  • Rainfall and rain detection
  • Detection of toxic gases in the air such as ammonia, sulfur compounds, benzene vapors, smoke and other harmful gases.
  • Accelerometer: vibration measurement

Case studies for decision makers:

  • Noise: Currently, measures to alleviate noise pollution has no objective basis because of a lack of specialized equipment. With the use of IoT in this case, real-time tracking enhances transparency in the handling of violations (violators are captured red-handed). Planning: measurement of noise cancelling quality of trees, barriers for people living near the highway.
  • Excessive light intensity affects human sleep as well as their privacy.
  • UV rays directly affect people’s health, especially diseases of the skin.
  • Temperature and humidity: (Planning) Changes on the surface of the walkway, causing radiation to people’s homes, increasing the temperature and influencing the surrounding humidity.
  • Rain and rain detector: Warning of rain so measures can be taken to protect property or deal with the weather.
  • Detection of toxic substances: Immediate warning to the people as soon as the poison appears locally.
  • Accelerometer: Measurement of vibration caused by public transport, construction (for handling of violations). Limiting the speed or traffic of large capacity vehicles at night to reduce vibrations affecting people’s health.

Lessons for students:

  • Types of pollution affecting people’s lives and their impacts on human health. For example, children growing up near highways are more likely to be agitated than those in quieter areas.
  • Noise: sound intensity and impact on hearing. Effects of trees on sound insulation.
  • Vibration: vibration of an object in physics.
  • UV rays: greenhouse effect (environment).
  • Rain: wind direction, rain direction in each season in the province (geography).
  • Detection of toxic substances: the speed of toxic substances spread (depending on wind, humidity, …)
