For the Royal International Miss 2020 Pageant, plans were in the making for several months and in spite of the COVID-19 virus, the state OK’d the convention and the hotel made every effort to ensure the safety of attendees. To avoid a person with the virus from entering the hotel and infecting attendees, a temperature […]
What does sensing above and sensing below look like?
This question certainly raises another, why do I need both? The answer to these questions starts with the goal of conserving water. The smart use of water to improve soil quality, especially in agronomic applications, requires optimal use of this precious resource. In-ground sensing has been used for many years and even enhanced with wireless […]
How can you get 5 different pressure sensor ranges from a single sensor?
Heating ventilation and air conditioning (HVAC) applications can use a wide range of full-scale, low-pressure sensors to address the variety of measurements involved in controlling and monitoring for maximum efficiency and performance. In a multilevel building, these measurements could include the use of differential pressure transmitters, a variable airflow volume (VAV) unit, a positive pressure […]
What sensors are in a smart HVAC system?
In addition to increased efficiency, a smart heating ventilation and air conditioning (HVAC) system will have many new features. Recent air flow requirements and proper room pressures to cope with the COVID-19 virus have brought increased interest to HVAC systems. Before COVID-19, one market research report forecast compound annual growth rate (CAGR) of 12.1% between […]
How can LiDAR be used to enforce social distancing?
The use of Lidar (Light Detection and Ranging) for automotive applications, especially autonomous vehicles, and aerial surveys is rather well known. With the COVID-19 pandemic, the technology has recently been applied to provide social distancing and help people transition to the new normal. For example, Quanergy has developed a Social Distancing Flow Management platform. It […]
How can employers help keep employees safe, especially in the hotel business?
Something is wrong, very wrong. Don’t panic. Hit the panic button. In 2018, to prevent violent assaults and sexual harassment of hotel workers, the American Hotel & Lodging Association (AHLA) created the 5-Star Promise aimed at strengthening safety and security for hotel employees and guests. Also, in and since 2018, ordinances have been enacted in […]
How has COVID-19 impacted 2020 sensor activity?
It’s June and for sensor people that has meant Sensors Expo in San Jose for many years. This year with the coronavirus dictating the terms, Sensors Expo has been postponed until Nov. 16-18 but it still will be held in San Jose, CA. Traditional pre-conference symposia, including Implementing Energy Harvesting and Higher Energy Efficiency Sensor […]
How can kirigami be used for sensing pressure?
If you are like me, you are aware of origami (the Japanese art of paper folding) but need a refresher on kirigami. Unlike origami figures that can only be made by folding, kirigami involves both folding and cutting. Inspired by kirigami, researchers at Texas A&M University developed 3D polymer-based kirigami architectures for microelectromechanical systems (MEMS) […]
Can a sensor detect COVID-19 in wastewater?
Wastewater-based epidemiology (WBE) that extracts data from urine and feces transported through sewers has the potential for communities to rapidly screen, quarantine and prevent the spread of COVID-19 caused by SARS-CoV-2 infection. As a result, many researchers are investigating its effectiveness for COVID-19 testing and to obtain information on health, disease and pathogens as well […]
Can a biosensor detect the COVID-19 virus in the environment?
Building on research for sensors to detect bacteria and viruses in the air, a team from Empa, ETH Zurich and Zurich University Hospital developed a biosensor to detect the new coronavirus (COVID-19). The sensor could be used measure the virus concentration in the air in real time in crowded locations such as train stations or […]
