The MAX30205 temperature sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analog-to-digital converter (ADC). Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. Communication is through an I2C-compatible, 2-wire serial interface.
 

The I2C serial interface accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behavior of the open-drain overtemperature shutdown output.

The MAX30205 features three address select lines with a total of 32 available addresses.

The sensor has a 2.7V to 3.3V supply voltage range, low 600μA supply current, and a lockup-protected I2C-compatible interface that make it ideal for wearable fitness and medical applications.
