Freescale aims accelerometer at preventive maintenance

Accelerometers intended for phones will not always hit the spot in industrial sensing, claimed Freescale at the launch of a family of them aimed at industrial preventive maintenance. Called FXLN83xxQ, the family is “designed to capture acceleration information often missed by less accurate sensors commonly deployed in consumer products such…

MEMS sensor detects height differences of 50cm

A pressure sensor which can detect height differences of as little as 50cm uses MEMS technology developed by Omron. The sensor module can measure altitude, atmospheric pressure or water depth in wearable electronics, activity monitors, industrial and marine instruments and mobile phones and cameras. The 2SMPB-01-01 absolute pressure…
