1. A body temperature monitoring device, comprising:
a wearable accessory, configured to be worn on a human body;
a thermal sensor, in the wearable accessory, and configured to measure a basal body temperature of the human body;
an acceleration detection device, in the wearable accessory, and configured to output an acceleration value, which includes an X-axis acceleration, a Y-axis acceleration and a Z-axis acceleration;
a display, on the wearable accessory, and configured to prompt an ovulatory phase; and
a processor, in the wearable accessory, and configured to
identify a wake up time of the human body based on the acceleration value,
control the thermal sensor to measure the basal body temperature at the wake up time,
record the basal body temperature measured every day, and
control the display to prompt the ovulatory phase when a temperature variation of the basal body temperature exceeds a temperature variation threshold,
wherein a measured temperature by the thermal sensor only before the Z-axis acceleration being detected is taken as the basal body temperature.
