Description

The MAX30205 is used to measure human body temperature. The MAX30205 digital thermometer temperature sensor is accurate to 0.1°C over the measurement range of 37°C to 39°C and the resolution is 16 bits (0.00390625 °C). The MAX30205 features an over-temperature alarm/interrupt or comparator mode for signaling a fan to turn on via OS output hysteresis. Power saving one-shot and shutdown modes are also available.
