How can sensors help cleanup waterways?

May 18, 2022 By Randy Frank

Twenty years after its first-generation design was introduced (2002), iRobot’s Roomba has spawned many competitors for indoor cleanup and made several advancements to its initial capabilities. Interactive Autonomous Dynamic Systems (IADYS) has applied the autonomous robot concept to address cleaner and safer water in rivers, canals, lakes, ponds, shipyards and more. IADYS’ Jellyfishbot autonomously collects […]

How is biomarker sensing expanding?

February 23, 2022 By Randy Frank

Pathogens, infectious agents that cause disease, can include microscopic viruses, bacteria, fungi and protozoa. Both biomarkers and biosensors can detect and identify pathogenic agents. After using biomarkers to measure and detect pathogenic factors and assess biological conditions., drugs can be delivered to the target tissue so that other tissues are not damaged. Biomarkers are widely […]

Can a dog’s sense of smell be duplicated? Part 1

December 9, 2021 By Randy Frank

Dogs’ sensitive noses and their ability to be trained to detect a variety of medical issues/diseases are well known. Using their sense of smell, trained dogs can detect lung, breast, ovarian, bladder and prostate cancers. For prostate cancer, dogs had a 99 percent success rate in detecting the disease in patients simply by sniffing urine […]

What is a Molecular Property Spectrometer sensor?

November 11, 2020 By Randy Frank

To measure and classify a wide range of combustible gases, NevadaNano has integrated multiple, complementary chemical sensors on a single silicon chip called the Molecular Property Spectrometer or MPS sensor. The chip’s patented array of micro-cantilevers with integrated piezoelectric sensing elements provides electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive […]

What is the Air Quality Index? Pt 2

September 13, 2020 By Randy Frank

With over 90 forest fires raging along the West Coast, you may feel safe and think you do not need to check the air quality index (AQI) if you don’t live in that region. Think again! A recent satellite image shows that the smoke already extends all the way to Michigan. Don’t smell any smoke? […]

What is the Air Quality Index? Pt 1

August 27, 2020 By Randy Frank

Depending on where you live, your age, sensitivity to airborne constituents and other factors, the air quality index (AQI) could be something that you monitor frequently. In the U.S., the AQI developed by the Environmental Protection Agency (EPA) is a nationally uniform color-coded index for reporting air quality. Air agencies use the AQI report and […]

What is a Sensor HAT?

August 22, 2020 By Randy Frank

HAT is a three-letter acronym (TLA) for hardware attached on top: the terminology used for a hardware specification for add-on modules for the Raspberry Pi model B+. With a HAT, no soldering is required, so the module simply plugs onto the Raspberry Pi. Taking advantage of this design concept and the popularity of the Raspberry […]

What sensors are in a smart HVAC system?

June 29, 2020 By Randy Frank

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 […]
