Building a smart city with low-cost IoT devices

Building a smart city with low-cost IoT devices

Most growing metropolitan areas are struggling to improve quality of life as pollution and congestion issues are getting worse each year. There are however many recent, low-cost devices which could contribute to better city planning and in return to sustainability and efficiency.

A typical application of IoT is to install a large number of low-cost, long range devices throughout the city and from there all environmental readings are fed into a database through the cloud. Using these measurements a detailed map can be created showing a detailed distribution of noise, pollution, traffic, energy consumption, etc. This is valuable data for city planners and decision makers of future developments.

To name a few common smart city applications:

  • Air quality, acoustic quality and meteorological readings.
  • Water quality management systems. Pipe pressure, water-flow and leak sensing minimising losses . Also chemical characteristics can be detected instantly to monitor quality.
  • Monitor energy consumption in public buildings and optimise readings according to date (e.g. power off computers instead of sleep mode, A/C usage optimization etc.)
  • Traffic control. Live traffic optimisation using cameras Smart parking system (e.g. dynamic, real-time feedback of parking spaces)

    In the upcoming months Team Brookvale will monitor air quality across Sydney to give a better understanding of air pollution. Make sure to follow our Facebook and Twitter page for updates.

    IoT enabled, cost effective air quality monitoring

    IoT enabled, cost effective air quality monitoring

    Air pollution in big cities is a huge problem and with the ever growing number of cars it’s getting worse each year. Road transport can be responsible for up to 80% pollution in urban areas. To put this in perspective each liter of fuel burnt is issuing up to 2 kg of CO2. If one’s daily average round trip is 20 km that equals roughly 1.5 tonnes of CO2 emission a year.

    Monitoring air quality is essential to provide information to citizens and to propose pollution reducing actions. Pollution monitoring has contributed to the introduction congestion taxes and in turn to a 20% reduction in CO2 emissions in cities such as Stockholm, London or Singapore.

    A purpose built circuit board with a gas sensor expansion kit, such as Waspmote, allows to monitor and determine quality of air by the following parameters: CO2, NO2, CO, CH4, H2S, Ethanol, Propane, Butane, Isobutane, Toluene, O3


    It’s a simple and cost effective IoT solution. With wireless 802.15.4 communication and a battery the board can operate for years reliably. Alarm at a certain threshold can trigger a notification on a mobile device or a computer.

    The air pollution IoT device can be completed with a range of other sensors such as UV, temperature, irrigation management, etc. Simple, cost-effective solutions like this helps to have a better understanding
