Sensors are becoming ubiquitous as their price and availability continue to improve. However, sensor data is not that simple and is prone to noise and other interference. The complexities of sensor data have led to sensor fusion that aims to perform better than a single sensor by improving the signal-to-noise ratio, decreasing uncertainty and ambiguity, […]

How are sensors improving maritime navigation?
Of course, GPS is important, but radar and the automatic identification system (AIS) use various sensors to track and report on ship positions in real-time. Sensor fusion is being developed for autonomous shipping. And there are hydrophones combined with other sensors and artificial intelligence (AI) and machine learning (ML) to identify and track whale movements […]
What is sensor fusion?
by Charles Pao, senior marketing specialist, CEVA Motion sensing devices are all around us and in several of the electronics that we use daily. Motion sensors are in earbuds – noticing taps to change songs or pausing music when we take them out of our ears. They’re used for head tracking in virtual reality (VR) […]
Sensor fusion levels and architectures
Sensor fusion is the process of combining inputs from two or more sensors to produce a more complete, accurate, and dependable picture of the environment, especially in dynamic settings. The goal of sensor fusion is to provide those improved results with the minimum number of sensors and minimum system complexity for the lowest cost. The […]
Sensor fusion – How does that work?
Each sensor type, or modality, has inherent strengths and weaknesses. Sensor fusion is the process of bringing together inputs from multiple sensors to form a single model or image of the environment around a platform. The resulting model is more accurate because it balances the strengths of the various sensors. Sensor fusion brings the data […]
How to design an effective telehealth system
By Marcel Consée, Mouser Electronics Healthcare can be deeply personal, and direct contact between patients and medical personnel remains vital. However, taking the relationship between doctors and nurses out of the equation can sometimes make sense. Medical crises such as the global COVID-19 pandemic accelerate the adoption of telehealth methods, even though the original idea […]
Sensors, sensors everywhere. Now what do I do?
By Moshe Sheier, Vice President of Marketing at CEVA Mobile computing has driven an explosion in product opportunities – smartphones, wearables, hearables, sports cameras, and more. Sensing will further extend opportunities in applications which must be environment-aware. Now it’s commonplace to think about object recognition and collision warning through visual, radar, or Lidar sensing. Short-range […]
How does sensor fusion improve an alarm system?
At Sensors Expo 2019, Tanja Hofner, a Principal Hardware Engineer for RF and Sensors in Infineon’s Power Management and Multimarket segment explains the operation of the company’s Integrated Alarm System demo. The demo uses two Infineon sensors: the digital XENSIV IM69D130 microelectromechanical systems (MEMS) microphone and a DPS310 digital barometric pressure sensor as well as […]
Robots are getting in touch
by Rudy Ramos, Mouser Electronics Often overlooked is the value of a sense of touch in robotics development. Designers focus strongly on discrete features such as power, freedom of movement, and machine vision. However, tactile sensing complements all of these and helps make the most of them. Having a sense of touch also adds unique […]
How can the power consumption for computing be reduced for energy harvesting?
At Sensors Expo 2018, Chet Jewan, vice-president of sales and business development from Eta Compute, explains how his company’s computing technology can benefit heart rate monitoring and energy harvesting applications. The first demo, with an Eta Compute chip running at 0.476V powered by solar energy, displays Jewan’s heart rate. A second demo has sensors being […]
