Motion sensor offers low-power settings
Susan Nordyk @ edn.com writes: Small enough for wearable devices, STMicroelectronics’ LIS2DW12 three-axis accelerometer draws only 50 nA in standby mode and 380 nA in low-power mode at a 1.6-Hz output data rate, adding negligible load on the battery. Operating from a supply voltage...
