Sensors are the cornerstone of building and home automation systems. They are designed for systems such as smoke detection, carbon monoxide (CO), organic compounds, motion, proximity, and light, to name a few. Renesas’ OB1203 sensor, with the appropriate algorithm, can determine a human’s heart rate, oxygen saturation (SpO2), respiration rate, and heart rate variability (a measure of stress). These features enable safe smart devices and/or systems.

System Benefits

  • Features the Renesas RA Family of high performance and cost optimized Arm®-based microcontrollers. The RA2A1 is well suited for low power and cost-sensitive applications, such as sensor hubs.
  • Supports various sensors for smoke, CO, temperature, humidity, indoor/outdoor/refrigerator air quality, light, and proximity detection. Up to six sensors can be connected via I2C.
  • Very few external components needed.
