Human Body Temperature Sensor Clinical Thermometer MAX30205 (±0.1°C)

The MAX30205 provides accurate clinical body temperature with an accuracy of 0.1°C (37°C to 39°C). MAX30205 provides one-shot, shutdown modes for reduced power consumption. MAX30205 features thermal alarm or thermostat temperature control with hysteresis.




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.
