In a battery-powered, wireless sensing node, the biggest energy consumer typically is the RF transmitter. The transceiver should have extremely low power in active, wait and even sleep modes. A one-second snapshot of the current consumption in the various portions of the transmission cycle shows the current draw of 15 mA for the 7.5-ms receive […]

How do sensors impact ATMs?
It’s well known that automobiles and smartphones have several sensors to improve today’s capabilities over those of previous generations. However, they are not the only products that impact consumers’ lives to do so. For example, automated teller machines (ATMs) have a surprising number and different types of sensors to perform a variety of functions. Even […]
New ultra-low power digital microphone; half the consumption, identical performance
For the third consecutive year, Infineon Technologies AG has successfully defended its market-leading position as MEMS microphone supplier. Moreover, Infineon’s market share rose to a staggering 45 percent as bare die microphone manufacturer in 2021 [1], according to recent research published by technology expert Omdia. This positive development is due to Infineon’s long-term experience in MEMS […]

How do you accurately measure skin color? Part 2
Measuring instruments for determining skin color have a variety of classifications. Telespectroradiometers (TSRs) and spectrophotometers (SPs) are two classifications for instruments that are widely used for measuring skin color. For example, in the cosmetic industry, TSRs are used for measuring color appearance for developing skin color charts and evaluating skin products. In contrast, SPs are […]
Smart sensor duo for mobile off-highway vehicles at ConExpo 2023
Elobau will once again be represented as an exhibitor at this year’s ConExpo. In South Hall 4, S85221, the German manufacturer of sensors and operator controls will present its new generation of tilt sensors with the N6 static and the N7 dynamic. The N6 static enables high-precision measurement under harsh environmental conditions, in stationary operations […]
Incremental encoders offer 16 quadrature resolutions from 96 to 4096
CUI Devices’ Motion and Control Group announced the introduction of a new series to its AMT incremental encoder family. Based on the existing AMT13 series package, the new AMT13A series is not subject to silicon-related lead time constraints and can serve as a drop-in replacement for AMT13 encoder models. AMT13A encoders offer 16 quadrature resolutions from 96 to 4096 PPR, […]
