Since 3D scanners have become more affordable, 3D scanning has changed the world of custom 3D printing. Once, 3D scanning was only used in military equipment and spacecraft parts production. With desktop and handheld 3D printers available for a few hundred dollars, 3D scanning has found a place in home fun and hobby projects. You […]
FAQ
Hybrid sensors for connected vehicles
The dependence of smart vehicle features on sensing technology has manufacturers thinking about how to field devices that combine functions in economical ways. Estimates are that today’s vehicles can have between 60 and 100 sensors onboard. And over the next decade the number of sensors is expected to double. No wonder, then, there are efforts […]
How does the PICMG IoT.1 specification for smart IoT sensors work?
The PCI Industrial Computer Manufacturer’s Group (PICMG) is developing a series of specifications to enable plug-and-play interoperability of smart sensors and effectors. The effort includes the large installed base of legacy non-IoT (not IP-enabled) devices and newer IoT-enabled smart sensors. The PICMG program includes development of a family of three IoT specifications. PICMG IoT.1 is […]
What’s the difference between 2-, 3-, & 4-wire RDT sensing?
The difference is measurement accuracy. Using 2-wire resistance temperature detector (RTD) sensing provides good accuracy (maybe), the accuracy of 3-wire sensing is better, and 4-wire sensing provides the best accuracy. In addition, there’s the option of using Wheatstone bridge topologies to improve the performance of 2- and 3-wire RDTs. This FAQ begins with a review […]
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 […]
Human presence detection and you
By Charles Pao, Senior Marketing Specialist at CEVA Mobile phones and tablets are getting more powerful, but if you’re serious about doing work (remotely), the dedicated work laptop still reigns supreme. Privacy and productivity have become increasingly important in this new paradigm of working anywhere. To help with both in the age of mobile computing, […]
What sensors are used in AR/VR systems?
A wide range of sensor technologies is required to support augmented reality and virtual reality (AR/VR) systems. Today’s AR/VR implementations are mostly focused on visual and audio interfaces and rely on motion tracking and listening/voice recognition sensors. That’s beginning to change with new types of sensors and various types of haptics being introduced. This FAQ […]
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 […]
How do sensors improve wind turbine performance?
Wind turbines are very complex machines. It takes a lot of sensors to ensure their continuous operation generating green energy. This FAQ reviews some of the sensors used to monitor wind turbine operations, such as: Eddy current sensors monitor the lubricating gap of the shaft, how the turbine shaft rotates both axially and radially inside […]
