content: Hello Everyone,I have a prototype of a light based heart rate sensor board that works on many types of skin colour, and can detect heart rate almost anywhere on your body. I am considering buying the parts in bulk so i can get the price really low, so if enough people are interested i can probably get them for £5/$8. Would anyone be interested in buying one if i go ahead?The board will be very tiny, possibly as small as 10mm (1cm/0.39inches) by 10mm.James

content: Easily Actually. I have tried them before, and they don't give you a good signal, especially if you have cold hands. Those sensors are designed to work on fingers and earlobes. I wanted something better and more consistent, which is when i came across an adaptable heart rate sensors that works on different skin colours and works on most parts of the body (So far tested on finger tip, wrist, forearm, bicep, neck, ear, forehead).

content: What might be hard to compete with are the free apps for android and iOS that do it. They seem to work pretty well. It's a clever "hack," as the kids today say.

content: Quote from: djacobow on September 27, 2015, 06:09:33 pmThat is one way to measure your heart rate, but a lot of people might want to do it automatically without having to load an app, as generally people get bored or forgetful, and i couldn't imagine it would be very convenient to hold you phone in front of you if you wanted readings longer than a minute or so. I am also not sure how accurate or reliable the app based heart rate sensors are, anyone have any experience with them?

content: I'd be interested. It would go well with a wearable project I have in mind, as long as it's small enough, which it sounds like it will be.

content: Sure there are free smartphone app, but this would be useful for a wearable product or other stuff. For example, how about a light saber that detects your heart rate and emits different sound :-) Good luck!
