High Accuracy MAX30205MTA MAX30205 Human Body Temperature Sensor Module Low Voltage Measuring Skin Wristband Temperature Sensor MAX30205MTA Product Features: Allows accurate temperature measurement Provides overheat alarm/interrupt/shutdown outputs. Uses a high-resolution analogue-to-digital converter Accepts standard I2C commands to read data, set overheat alarm (OS) trip thresholds, and configure other features I2C-compatible interface with lockout protection, making it ideal for wearable fitness and medical applications. Product Parameter Description: The module is based on the MAX30205, a temperature sensor that accurately measures temperature and provides an overheat alarm/interrupt/shutdown output. The device uses a high-resolution analogue-to-digital converter (ADC) to convert temperature measurements to digital form. An I2C-compatible two-wire serial interface allows access to the conversion results. The device accepts standard I2C commands to read data, set overheat alarm (OS) trip thresholds, and configure other features. When reading the temperature register, any changes in temperature are ignored until the read is complete. When the read operation is complete, the temperature register will be updated for a new temperature measurement. The MAX30205 has three address selection lines for a total of 32 available addresses. The sensor has a supply voltage range of 2.7V to 3.3V, a supply current as low as 600µA, and a lockout-protected I2C-compatible interface, making it ideal for wearable fitness and medical applications. The MAX30205 measures the temperature of its own core temperature. The thermal path between the chip and the outside determines the accuracy of the temperature measurement. The external temperature is conducted to the chip temperature primarily through the leads and exposed pads. Therefore, the device is most likely to measure PCB temperature. For ambient temperature measurements, mount the device on a PCB (or part of a PCB) that is at ambient temperature. Due to the low supply current, device self-heating has the least effect on the temperature error. The configuration register contains 8 bits of data and initiates a single transition (ONE-SHOT), enables bus timeout, shutdown control, fault queue set, data format set, selects OS polarity and determines whether the OS outputs will operate in comparator mode or interrupt mode.
