The direction sensing apparatus for the moving body is provided to easily confirm the traveling direction of intruder by using the position relation between the intruder and a pair of dual type hotwire device. The first and second dual type thermocouple devices(10,20) having a pair of sensor are arranged with predetermined interval to detect the intruder. The detection signal of the intruder generated in the first dual type thermocouple device is amplified by the primary amplification section(12). The thermocouple detection signal transmitted after the first noise removal part(14) is transformed with the first sine wave circuit(16). The first thermocouple signal (z1) is inputted to the judgment circuit(30) to remove the noise mixed in the signal amplified in the primary amplification section of the signal waveform. The judgment circuit is combined with the first thermocouple signal and the inputted second thermocouple signal. |
