Overview

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 new high performance and cost optimized family of Arm®-based microcontrollers (Renesas’ RA family). 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.
