how to use low-cost sensors to provide real-time, local-scale air quality information. EPA and state and local agencies face persistent challenges meeting such air quality information needs, including challenges in understanding the performance of low-cost sensors.

At the micrometer-centimeter scale, electrochemical and optical probes have been productively used to profile gradients in pH, redox, and oxygen; however, these probes and their associated equipment are intrusive to the ecosystem and often expensive, limiting their application to only a few point measurements or limited time series, and their fragile nature makes them best suited for laboratory use

3D Sensors — What Is Out There?

ities globally have common objectives regarding the safety, healthcare, and education of their communities, as well as the delivery of services in the form of utilities and transportation networks. The growth of ICT is enabling cities to better meet these objectives, allowing for smart solutions that aim at developing the urban ecosystem while managing assets and resources efficiently. “There is no clear definition for what constitutes a smart city, but typically we think of it as a city that “gets you” and addresses needs and challenges in an intelligent way,” says Diender. “For example, it’s a platform that links initiatives by government, giving insight to officials who need to anticipate challenges and take action, while driving things forward in an accessible way.” An example of this might be street lights with built-in motion sensors that allow the lights to turn off and save power until movement of a vehicle or pedestrian is detected. “These motion sensors might take the form of a camera, which could also act as an additional eye for the police,” adds Diender. “If you add advanced image recognition to those cameras, they could even detect flooding in the streets and identify water leaks. In this instance, you’ll have one smart device talking to three industries – security, lighting, and water.”

Telecom operator Orange announced on Wednesday that it has completed the first stage of the Smart City Alba Iulia 2018 pilot project. In this framework, 14 innovative technological solutions were implemented within only one year. According to a communiqué of Orange, at present in Alba Iulia there are over 600 sensors which, together with fixed and dedicated mobile communication networks, create a digital infrastructure of the city. Thus, the City of the United States owns broadband Internet networks, 4G / 4G +, Wi-Fi and LoRaWAN, provided by Orange Romania and secured through the Business Internet Security platform. In addition, the Wi-Fi network includes over 228 access points to the city and city and 15 access points to public transport. "In almost one year of Wi-Fi hotspots on buses, about 8% of the 60,000 Alba Iulia population has accessed the service, generating more than 1 TB of data in 30 minutes' sessions, notes Orange in the release.
