Blood Pressure Monitor

Overview

Renesas proposes a suitable solution for blood pressure monitoring by the high precision analog and software technology. In particular, RL78/H1D series have on-chip high-precision analog front end, LCD controller and PWM timer that are ideal for blood pressure measurement. They achieve pressure monitoring system with simply connected pressure sensor, cuff, pump, valve, LCD panel.
