Breath Detection Device, Mobile Terminal and Time Display Device

摘要

A breath detection device includes a breath-blowing unit in which breath is blown; a deflection amount sensor that detects pressure of the breath-blowing unit; a temperature sensor that detects a physical amount (temperature) different from the pressure of the breath-blowing unit; a storage unit that stores a determination reference which is a reference to determine whether or not breath is blown into the breath-blowing unit; and a determination unit that compares a detection result which is detected by the deflection amount sensor and the temperature sensor with the determination reference, and determines whether or not breath is blown into the breath-blowing unit.

1. A breath detection device comprising:
a breath-blowing unit in which breath is blown; a pressure detection unit that detects pressure which is received by the breath-blowing unit, and outputs a signal; a physical amount detection unit that detects a physical amount different from the pressure and outputs a signal; a storage unit that stores a determination reference which is a reference to determine whether or not breath is blown into the breath-blowing unit; and a determination unit that compares the signal which is output from the pressure detection unit and the signal which is output from the physical amount detection unit with the determination reference, and determines whether or not breath is blown into the breath-blowing unit.
