When the infrared thermometer is aimed at the object being measured, the infrared sensor collects the temperature data, converts it into an electrical signal, amplifies it through an operational amplifier, and then performs AD conversion. The converted results are transmitted to the MCU via a communication interface and are finally displayed on an LCD segment code screen.

Application Advantages of the N32L406 Chip:

• Utilizes a high-performance Arm® Cortex®-M4 core MCU, offering fast processing speeds and strong computational capabilities.

• The chip supports an operating temperature range of -40 to 105℃, with 4kV ESD protection, ensuring high reliability.

• With a 12-bit resolution, the ADC's maximum sampling rate can reach 4.574 Msps, enabling high-precision sampling.

• The chip features an extensive 128KB on-chip Flash memory, eliminating the need for external storage.

• The MCU supports various low-power operating modes, including RUN, LOW-POWER RUN, SLEEP, LOW-POWER SLEEP, STOP2, and STANDBY, extending battery life.

• The chip includes an LDO to power the LCD segment code screen and buzzer independently from the temperature detection circuit, allowing the temperature detection circuit to be activated as needed through software, optimizing dynamic power consumption.
