Infrared (IR) contactless thermometers represent a safe and efficient method for temperature measurement. These devices, which do not require skin contact, offer the advantage of swiftly and accurately determining temperature, provided they are used within the specified range and close to the forehead. With the emergence of new viruses, the demand for such contactless thermometers has surged significantly.

The IR contactless thermometer reference design by Renesas features a combination of critical components: the RL78/H1D, a microcontroller unit (MCU), the ISL9205D, a Lithium-ion battery charger, and the ISL9021A, a Low Dropout Regulator (LDO). This integration of technologies provides a comprehensive solution for developing IR contactless thermometers.
