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 does a finger unlock a door?
At Sensor Expo 2019, Marcia Ratton from TDK InvenSense demonstrates how the UltraPrint Sensor (TCFS-3000) precisely identifies a finger print. Integrated into a door lock, the image from the sensor is displayed on a screen to demonstrate the clarity and details of the image. The ultrasonic fingerprint imaging uses proprietary InvenSense, a TDK Group company, […]
How can an RTC feature stabilize an image sensor’s output?
At Sensors Expo 2019 in San Jose, CA, Sahil Choudhary, a product marketing manager at InvenSense, demonstrates how the real-time clock (RTC) feature in his company’s 6-axis (accelerometer and gyroscope) sensors provides accuracy and stabilization for critical imaging applications. For a specific device frequency, say 10 Hz, the RTC input ensures that the 10 Hz […]
