At Sensors Expo, Eric Biel, an engineer from Powercast Corporation, explains how radio frequency or RF energy can be used in energy harvesting applications. RF wireless power transmitted by the PowerSpot transmitter is received by two receiver sticks with LEDs. The TX91503 PowerSpot transmitter broadcasts an RF signal in the unlicensed 915 MHz industrial, scientific […]
Frequently Asked Question (FAQ)
What can you do with a water-resistant pressure sensor?
At Sensors Expo 2018, a product marketing engineer for ST Microelectronics demonstrates how a water-resistant pressure sensor mounted on a printed circuit board (PCB) can be submerged in water and provide accurate readings. With this capability, it has potential applications in wearable devices, altimeters and barometers for portable devices, GPS applications, weather station equipment, Industry […]
How can asynchronous power produce longer battery life?
At Sensor Expo 2018, Paul Washkewicz, Vice-President of Marketing for Eta Compute explains how his company’s application-specific integrated circuit (ASIC) uses asynchronous logic to lower the power to the microcontroller unit (MCU) to extend battery life. The ASIC is based on an ARM M3 and has a CoolFlux digital signal processor (DSP) from NXP in […]
How can sensing be distributed in a smart building?
At Sensors Expo 2018, Masakazu Shiinoki, a field application engineer from the MEMS Sensor Business Unit of Omron shows how different microelectromechanical systems (MEMS) sensing technologies can be used in a building. The three (ground, first and second) floors use barometric (absolute pressure), airflow and differential pressure sensors. In addition, the first floor has an […]
How do you design a winning pressure sensor demo?
At Sensors Expo 2018, Caleb Kim from ROHM Semiconductor explains a visually intriguing display in his booth. A ROHM pressure sensor was used to build a game. Whenever the ball portion of the game is struck, the pressure sensor attached to the ball measures the difference in pressure. The harder the ball is hit, the […]
How can you track vibration?
At Sensors Expo, Pete Hulbert, a Test & Support Engineer from Silicon Designs explains one of the applications of his company’s industrial grade microelectromechanical system (MEMS) accelerometers using a tabletop track with moving cars. Three accelerometers are attached to the track in different locations (turns in the track) to determine the vibration in the track […]
How can you get digital temperature data?
At Sensors Expo 2018, Mike Mays from Analog Devices explains the LTC2983, a temperature to bits IC. The IC is designed to be extremely easy to use part. Everything necessary to measure temperature is performed by the chip and its output is in direct degrees C. In the display, an “EMI (electromagnetic interference) Hairball from […]
What’s new in microcontrollers for sensing?
At Sensors Expo 2018, Jason Wellman from the 8-bit marketing division at Microchip Technology demonstrates the noise improvement and other capabilities of the advanced analog to digital converter (ADC) on the company’s recently introduced ATmega4809 microcontrollers (MCU). As a Core Independent Peripheral (CIP), the ADC filters and averages random noise as well as periodic noise […]
How can sensors make a smart ball?
At Sensor Expo 2018 in San Jose, CA, an expert from NXP Semiconductors describes the Internet of Things (IoT) smart ball demo that NXP had in its booth. Sensors in the ball provide real-time data and the system can publish the data to the cloud using IBM Bluemix Services. The data includes 3-axis measurements from […]
How fast can a MEMS pressure sensor respond?
At Sensors Expo 2018, Giovanni De Majo from audio and pressure sensor product marketing at ams AG, discusses the company’s pressure sensor demo. Using two pressure sensors, the demo indicates relative height. Manually moving the pressure sensor up a measuring stick that shows the height change, a display also provides a continuous measurement from a […]
