MAX30205
MAX30205 is Human Body Temperature Sensor manufactured by Maxim Integrated.
Human Body Temperature Sensor
General Description
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 highresolution, sigma-delta, analog-to-digital converter (ADC). Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. munication is through an I2C-patible, 2-wire serial interface.
The I2C serial interface accepts standard write byte, read byte, send byte, and receive byte mands to read the temperature data and configure the behavior of the opendrain 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-patible interface that make it ideal for wearable fitness and medical applications.
This device is available in an 8-pin TDFN package and operates over the 0NC to +50NC temperature range.
