Maxim Integrated / MAX30205_Clinical_Temperature_Sensor

Maxim Integrated MAX30205 C, C++ source code driver software: MAX30205 is accurate to +-0.1°C over the range of 37.0°C to 39.0°C. One-shot, shutdown modes are available for reduced power usage. Thermostat thresholds allow for temperature hysteresis or for alarm settings. The MAX30205 is available in a compact 3x3 mm, 8-pin TDFN package. Operating supply voltage range is 2.7V to 3.3V. Typical applications are for clinical digital thermometers, thermostats with hysteresis, and temperature alarms.
