Description: The is a low profile module designed specifically for heart
ratemeasurement purposes. It consists for four discrete light emitting diodes and a photodiode detector
IC optically isolated by light barriers to eliminate cross talk. The photodiode detector IC features an IR
block photodiode connected to a current amplifier that outputs an amplified current linearly related to the
photodiode current. This integrated module will create a low-noise output current for external analog
signal processor to generate accurate hear rate signals.
Four independent LEDs are provided for external drivers to enable different driving configurations in pair or any combination to achieve more accurate measurement or to implement different functions of a biosensor.
