Product Description
The module adopts MAX30205 body temperature sensor, which can accurately measure body temperature and provide overtemperature alarm/interrupt/turn off output. High resolution Trigonometric integral analog-to-digital converter (ADC) is used to convert body temperature measurement data into digital form. Communicate through I2C compatible 2-wire serial interface. The I2C serial interface can accept standard writing section, reading byte, sending byte, and receiving byte commands to read temperature data and configure the behavior of open drain overheat shutdown output. MAX30205 has a locking protection I2C compatible interface, suitable for wearable fitness and medical applications.
Parameters:
Power supply voltage: DC 2.7V~3.3V
Accuracy: 0.1 ° C Accuracy (37 ° C to 39 ° C)
Temperature resolution: 16 bits (0.00390625 ° C)
Communication method: I2C communication
Working current: 600 µ A (typical value)
Default I2C address: 0x48
Description of OS overtemperature shutdown output pin: When the MAX30205 sensor temperature is below 80 ℃ (excluding 80 ℃), the OS outputs a high level of about 3.2V; When the temperature of the MAX30205 sensor reaches or exceeds 80 ℃, the OS outputs a low level 0V.
Usage method
Open the test program max30205demo.ino in the data. After the upload is successful, open the serial port monitor. The Baud is 9600. Place your finger on the chip of the module, and you can see that the temperature read in the window will rise
