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 […]

How can you quickly integrate an Ozone sensor into your final design?
First, you must have an ozone sensor that meets your application’s requirements. Must haves could include: Measurement Range 0 to 20 ppm Lower Detection Limit <0.1ppm Resolution <0.1ppm Accuracy <± 2% of reading Small Size with Low Profile (15x15x3mm) Long Life (10 years expected life) Fast Response (15 seconds typical) Long Term Stability (50 ppm […]
What is the Air Quality Index? Pt 2
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
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?
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?
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 you ensure proper air quality levels in buildings?
In the building management industry, landlords and building managers are charged with the safety and comfort of the tenants within their apartment complexes or office space. Safety includes ensuring that proper air quality levels are maintained. One of the ways to do this is by preventing a silent offender of public safety issues, carbon dioxide […]
How do sensors make a building more comfortable?
Temperature is certainly the most obvious answer but there are other sensors that are increasingly being employed in the smartest homes and buildings. With the right sensor inputs, several actions can be taken by actuators to increase health/safety as well as comfort. In addition to temperature measurements, pressure, humidity and air quality sensing in ducts […]
