The ArduIMU V4 is an Arduino based integrated measurement unit that offers a complete wireless sensor module that started as an open source project by 3DRobotics back in 2007.

The sensor is intended as an alternative to pyroelectric sensors or PIR detectors in home automation, building automation, healthcare, security and industrial applications. Typically human presence ...

A high-quality measurement of the human heart signal was demonstrated using this optical sensor. The sensor's suitability was thus proven for biomagnetic measurements in the picotesla range.

The Withings Body Scan scale uses electricity to measure body and body part metrics, going beyond just weight measurement.
