Body Temperature Measurement in Access Control Systems

Renesas’ design solution measures body temperatures accurately and can be integrated into access control systems easily

Image of Renesas’ Winning Combination - Body Temperature Measurement in Access Control SystemsRenesas’ winning combination body temperature measurement systems are a healthy and safe way to measure body heat. Compared with common IR contactless thermometers, they can measure with longer distance (>50 cm). Users of this solution can measure body temperatures accurately and quickly and the solution can be integrated into access control systems easily. The RL78/G13 is a standard 16-bit microcontroller (MCU) with low power, low cost, and an abundant lineup of features.

This system incorporates the ISL29501 time of flight (ToF) IC to provide an efficient solution that is easy to design and control, while also providing accurate wide range distance measurement. With a high-performance LDO, this reference design provides a reliable power system.
