Title:
TEMPERATURE SENSOR, LIVING BODY HEALTH MANAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/072714
Kind Code:
A1
Abstract:
It is possible to provide a temperature sensor capable of reducing the sensor size and weight and save power. The temperature sensor (210T) includes a plurality of sets of bimetal cantilever sensors (211) having lever 212 stepwise different. For example, when the temperature increases and the temperature has reached a predetermined value decided by the length of the set of the levers (212), the lever (212) is brought into contact with an electric contact member (214) so as to turn ON an output signal from a detection circuit (215b) in a signal processing circuit (215). Thus, in the sensor control unit, when the temperature continuously increases, for example, output signals are successively outputted from the respective sets of signal processing circuit (215) in the descending order of the lengths of the levers (212).
