Researchers from the Indian Institute of Technology Madrashave proposed a magnet-based sensor that would allow scientists to measure the velocity of blood pulse waves within the carotid artery. Each ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Pulse oximetry is a ubiquitous non-invasive medical sensing method for measuring pulse rate and arterial blood oxygenation. Conventional pulse oximeters use expensive optoelectronic components that ...

This file type includes high resolution graphics and schematics when applicable. When the need arises to convert voltage readings from an analog sensor into a pulse train, a low-end microcontroller ...
