The FPGA-based platform is critical for producing an inexpensive early validation platform design. In past years, sensor nodes based on the FPGA platform have been proposed to be IoT low-end devices. In this study, we present the FPGA based IoT low-end reconfigurable pulse sensor interface design that can be integrated with a multi-sensor healthcare platform to monitor a human pulse vital sign and be able to distinguish between user normal, Bradycardia, or Tachycardia heart rate. The pulse sensor interface is implemented by VHDL programming and FPGA technology. The designed pulse sensor peripheral interface is reliable and reconfigurable. It can collect vital body signs with the accuracy of a 15 nanoseconds period. The peripheral in FPGAs embedded system has been tested by placing the biosensor on the user’s fingertips. The BPM can be updated every 15 seconds.
