Activities Empowering Ruston City Services Using Wireless Sensor Networks The City of Ruston, Louisiana has a number of ongoing projects to improve the quality of life for its residents, including a Smart Grid system and a downtown fiber optic network. Louisiana Tech University plans to develop low-cost improvements to city services using the fiber-topic and small cell installations to enable smart transportation, smart weather, and smart flood risk monitoring and notification capabilities that can be viewed via a Smartphone App. We also plan to study the use of smart re-closers, wireless connectivity, and solar power potential. Secure Cloud Architecture SC3-cpSriA Smart cities run largely on cloud services for efficiency and affordability reasons. Residents, government agencies, and small and medium businesses can benefit from an Architecture or Framework for privacy and rights-inclusive security practices across smart city and community cloud services. First, the City of Syracuse, New York, USA, in cooperation with Syracuse University and SC3-cpSriA Action Cluster(Smart City and Community Challenge Cloud privacy security rights inclusive Architecture) consider how the Architecture guidelines may apply. The SC3-cpSriA Action Cluster welcomes new members to broaden the debate. First, smart streetlight networks, catch basin monitoring, and water metering projects may consider if and how security, privacy, data protection and rights-inclusive cloud architecture guidelines may be followed. The ethics for facial recognition, machine learning and artificial intelligence systems and cloud services in future smart cities with privacy, security and rights-inclusive architecture will also be reviewed. Can architecture guidelines help protect citizens rights and encourage growth of smart city open data lakes, encouraging civic engagement and data privacy security and rights-inclusive innovation, entrepreneurship and economic development? Press How Santiago’s Las Condes commune is improving quality of life through sensors Mayor of Las Condes, Daniela Peñaloza Ramos, explains how sensors and IoT are transforming the city into a safer, more sustainable, and more liveable space for citizens.

Sensor technologies play a crucial role in smart systems by providing real-time data on the status and conditions of these systems, enabling them to make decisions and take actions based on the data received.

Technologies

Some examples of sensor technologies used in smart systems include:

• Temperature, Humidity and Pressure sensors: These sensors are used to collect data on the environment and infrastructure systems.
• Smart cameras and video analytics: These technologies are used for monitoring and surveillance, such as detecting objects and people, tracking movements, and identifying patterns and anomalies.
• LiDAR and radar sensors: These sensors are used to detect and measure objects and features in the environment, such as traffic, pedestrians, and obstacles.
• Acoustic sensors: These sensors are used for sound detection and analysis, such as speech recognition, sound localization, and noise reduction.
• Infrared and thermal sensors: These sensors are used to detect heat and temperature variations, such as in industrial processes, building energy management, and medical applications.
• Magnetic and electromagnetic sensors: These sensors are used to detect and measure magnetic fields, such as in navigation, robotics, and metal detection.
• Chemical and gas sensors: These sensors are used to detect and measure specific chemical compounds or gases, such as in environmental monitoring, industrial process control, and medical diagnostics.
• Force and pressure sensors: These sensors are used to detect and measure physical forces and pressures, such as in robotics, industrial automation, and human-computer interaction.
• Biometric sensors: These sensors are used to measure and analyze biological and physiological data, such as fingerprints, facial recognition, and heart rate monitoring.

All these sensor technologies provide a rich source of data that can be used to improve the performance, efficiency and intelligence of smart systems, by enabling real-time monitoring, decision making and control, predictive maintenance and optimization of resources. These sensors come in various sizes and packages including micro-sensors that can be dispersed in the environment to monitor specific conditions and send data back to a central hub often called smart dust.

Smart City Infrastructure

We define a smart city as one that has purpose (sustainability, equity, traffic safety) to its planning and measures results of its actions towards achieving that purpose. For this reason we consider three elements fundamental to a smart city: (1) A planning process based on a deep understanding of the needs of the community, (2) A set of metrics to measure progress, and (3) A data platform to enable data collection and measurement against metrics. A smart city is therefore a dynamic city that makes living in a dense urban environment more civil and more rewarding.

A smart city is not only attractive to people who live there, but to people who visit and companies doing business there. As already explained, we consider a data platform to enable data collection and measurement against planning metrics to be fundamental to a smart city. The goal is to make decisions based on data. Such a platform would enable a real time response to demand, events and emergencies. It would allow planners to make sure the city’s budget is used as effectively and efficiently as possible to meet the city's goals. This represents one way that cities can break down silos and use data intelligently so that government operates as a true enterprise, rather than as a series of loosely linked departments and agencies.

Through greater data availability citizens can be better engaged, and system managers can see further and more holistically.

Precision Farming

Sensors are widely used in precision farming to gather data on various aspects of crop growth and soil conditions, which can then be used to optimize irrigation, fertilization, and pest management. Some examples of how sensors are used in smart agriculture include:

• Soil moisture sensors: These sensors are used to measure the moisture content of the soil, which can then be used to optimize irrigation schedules and reduce water waste.
• Crop sensors: These sensors are used to measure various aspects of crop growth and health, such as leaf temperature, chlorophyll content, and plant height. This data can be used to optimize fertilization and pest management.
• Weather sensors: These sensors are used to measure various weather parameters, such as temperature, humidity, precipitation, and solar radiation, which can be used to optimize irrigation and fertilization schedules, and to predict crop yields.
• Air quality sensors: These sensors are used to measure the concentration of pollutants in the air, such as carbon monoxide, nitrogen oxides, and particulate matter, which can be used to monitor the air quality and to optimize crop growth conditions.
• Drones and aerial imaging: Drones equipped with cameras and other sensors are used to gather detailed information on crop health and growth, as well as to survey fields for pests and diseases.
• Automation and robotics: Automated tractors, self-driving vehicles and other forms of automation and robotics are increasingly being used in precision agriculture, allowing farmers to more efficiently and effectively manage their operations.
• Artificial Intelligence and Machine Learning: AI and ML are increasingly being used to analyze the data generated by precision agriculture technologies, to help farmers make more informed decisions and optimize their operations.

All these sensor technologies provide a rich source of data that can be used to improve the performance, efficiency and sustainability of agricultural systems, by enabling real-time monitoring, decision making and control, predictive maintenance, and the optimization of resources.
