Introduction
The MAX30205 launched by Maxim Integrated is a digital human body temperature sensor that can be used on development boards such as Arduino and ESP32. The working principle is as follows:
- Temperature detection principle: The MAX30205 uses high-precision microprocessors and sensor technology to measure the temperature on the human body surface and convert it into a digital signal.
- Digital signal processing: The chip inside the sensor processes the collected temperature data to obtain more accurate and stable temperature values.
- Communication interface: The MAX30205 features I2C and SPI interfaces, enabling communication with controllers such as Arduino, thereby providing reliable data transmission. ·Feedback mechanism: The MAX30205 also features a feedback mechanism that can automatically calibrate sensor errors, ensuring the accuracy and reliability of temperature measurement.
