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 in the ball?
On August 20, in the third round of the BMW Championship golf tournament, an attendee put a remote-controlled golf ball on the 15th green where professional golfers Rory McIlroy and Scott Stallings were putting and tried to navigate it into the hole. After two failed attempts from McIlroy to knock the ball away with his […]

What metrics can bioelectrical impedance analysis provide? Pt 2.
With biosensing analog front end (AFE) ICs available from several major suppliers, researchers have a variety of options to investigate more sophisticated health measurement and monitoring techniques for healthcare professionals as well as users. Some of the applications currently under active investigation include identifying acute tissue injury and skeletal muscle fatigue, assessing neuromuscular disorders, tracking […]
What metrics can bioelectrical impedance analysis provide? Pt 1.
Healthcare and fitness are increasingly important to many people. The ease of making measurements or showing improvement metrics and the amount of data that can be provided by a minimal, non-invasive process makes the ongoing effort sustainable. Bioelectrical impedance (or bioimpedance) analysis (BIA) provides users with a technique that is easily integrated into smart watches […]
How can you easily evaluate a MEMS microphone ?
Microelectromechanical systems (MEMS) technology is used for many sensing applications including microphones. The MEMS microphone provides a design alternative to Electret Condenser Microphones (ECMs) for many consumer electronic and mobile products. With this goal in mind, Infineon Technologies silicon microphones have been designed to extend the benefits of lowest possible self-noise (high SNR) and lowest […]
Redundant, half-bridge TMR-based sensor handles safety-related angle and position detection
TDK Corporation expands its tunnel-magnetoresistance (TMR) angle sensor portfolio with the launch of the TAS4240 TMR-based angle sensor for automotive and industrial applications. The TAS4240 comes in a compact TSSOP8 package and provides two redundant analog single-ended SIN/COS outputs. The sensor enables precise angle measurements in applications where high performance is needed and space is […]
What are the types and uses of position sensors?
Position sensing is a critical function across a wide range of applications, from robot drive chains to conveyor belts in supply chain operations to the swaying of wind turbine towers. It can take many forms, including linear, rotary, angular, absolute, incremental, contact, and non-contact sensors. Specialized sensors have been developed that can determine positions in […]
What are emerging sensor technologies for Agriculture 4.0?
Agriculture 4.0 is emerging and requires an expended sensor suite. Agriculture 4.0 refers to systems that employ drones, robotics, the Internet of Things (IoT), vertical farms, artificial intelligence (AI), renewable energy, and advanced sensor methodologies. Agriculture 4.0 is similar to Industry 4.0 in some ways: Where Industry 4.0 is designed to support automation and mass […]
How can low-cost sensors help address climate change?
According to the recent IDTechEx report “Printed and Flexible Sensors 2022-2032: Technologies, Players, Markets,” low cost printed/flexible sensor technologies could play a significant role in adapting to climate change [1]. Adapting could take various forms, from changing the areas in which specific crops are grown to building flood defense systems and even relocating cities in more […]
