Measuring air quality, like any other measurement process starts with the sensors. The sensors provide the concentration of different elements in the air such as CO2 and volatile organic compounds (VOCs) as well as other parametric data such as humidity, temperature, atmospheric pressure and light level that affect the ambient environment indoors – or outdoors. […]

What’s an acoustic leak detector?
Acoustic leak detection sensor technologies rely on the fact that liquid and gas leaks are noisy. However, it’s not necessarily a noise that the human ear can detect, it can be in the ultrasonic region. Leaky water pipes are a significant environmental challenge – UN Sustainable Development Goal No. 6 states that clean (drinking) water […]
What sensors are used in today’s and tomorrow’s HVAC systems? Part 1
When Willis Carrier designed a system of fans, ducts and perforated pipes, which became the first modern electric air conditioner (AC) in 1902 (120 years ago), sensing was not part of the bill of materials. Devon Brock, Manager of Product Knowledge and Training, Sensors Group at TE Connectivity provides some insight into subsequent AC systems. […]
high-precision pressure transmitters feature extremely low-profile design
TDK Corporation presents the AVD series of new pressure transmitters, distinguishable by their extremely low-profile design and high precision. The transmitters with B58621V* ordering codes are available in three versions for different pressure measurement ranges including 0 to 16 mbar, 0 to 100 mbar, and 0 to 7 bar. The series offers high precision levels […]
How can you sense ripening fruit?
A diet high in fruit (and vegetables) can reduce the risk of developing heart disease, cancer, inflammation and diabetes. But the fruit needs to be fresh for a sustainable, healthy diet. Several techniques are being used to detect ripening fruit. One company, smartGAS in Germany, has two different sensors to detect the ethylene (C2H4) that […]
Tiny CO2 sensor from Infineon Technologies bestowed Switches & Sensors LEAP Award
At four times smaller and three times lighter than its NDRI counterparts, the tiny XENSIV PAS CO2 sensor from Infineon Technologies captured the judges’ attention, earning it the LEAP Award in Switches & Sensors. More than 100 entries were received for the annual competition which celebrates the most innovative and forward-thinking products serving the design […]
Hydrocarbon sensor eliminates need for maintenance during 10+year lifetime
NevadaNano announced the “MPS Mini” a miniaturized version of the highly popular Molecular Property Spectrometer (MPS) Flammable Gas Sensor. The new sensor is the world’s most accurate hydrocarbon sensor in its class and eliminates the need for maintenance during its 10+year lifetime. The sensor will debut this week at Sensors Converge in Booth #733. The […]
Gas sensor for multiple applications detects propane leaks
NevadaNano announced its Molecular Property Spectrometer (MPS) R-290 Propane sensor. The new device is the most accurate on the market, making it an ideal solution for residential and commercial R-290 propane applications including air conditioning, vending machines, commercial refrigeration racks, and clothes dryers. According to Reports and Data, the Global Natural Refrigerants Market, which includes […]
How can CO2 sensing help overcome COVID-19?
One sensing tool that has played an important role since the beginning of COVID-19 is data logging. Data loggers use a wide variety of sensors to measure everything from temperature to illuminance. One specific type of data logger equipped with a CO2 sensor has been used since the beginning of the pandemic to monitor and […]
4-in-1 MEMS sensor measures gases, humidity, temperature and barometric pressure
Whether at home, in the office, or outdoors, we need to be confident that the air around us is clean and safe to breathe – COVID-19 has clearly highlighted the importance of air quality. Due to the particulates, gases, and even airborne viruses ubiquitously present in our modern environment, poor air quality has an increasingly […]
