Hello, I am building a heart rate monitor, which measure the heart rate through the temple vein blood pressure.
Initially I thouth for this item but my delusion is very high when I notice it's very noisy and quite non accurate; so I am asking if you know something else.
It's not important if it will be more expensive, cost is not a problem; which I need is a very accurate and affordable sensor.
Thanks for replying me...
Simply I use a Pulse Amped Sensor (SEN-11574) I bought on Amazon, but I am very disappointed in using it.
I tried AD8233 also (SparkFun Single Lead Heart Rate Monitor - AD8232 - SEN-12650 - SparkFun Electronics ) but this board does not fit my needs because my goal is to measure heart rate monitor from vein blood pressure of the temple.
Any help will be very appreciated.
