Optical Heart Rate Monitor Kit

OHRM 3D ModelWe are excited to announce that EWH's new Optical Heart Rate Monitor (OHRM) Kit is available for online orders. The circuit measures the heart rate through the subject’s fingertip and shows the cardiac frequency through a blinking light. The product teaches students principles of electronics and biomedical engineering through hands-on learning and is ideal for middle/high school and college students, or for students training for careers in electronics, BMET, and healthcare occupations. The kit includes a bare board and electronics components, which can be reused for multiple assemblies.

Engineering World Health’s Optical Heart Rate Monitor Kit is an educational tool only and is not to be used for any other purpose, including any medical, diagnostic or other laboratory applications.
