Wireless Sensor Hub

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. 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 are needed.
