Pyroelectric infrared radiation detector |
摘要 |
A pyroelectric infrared radiation detector is capable of removing internal noise generated in a pyroelectric element as well as noise due to a power source in the manner that the induction noise of exterior high-frequency noise due to an inductance component in an outer lead wire is removed by connecting a second filter to a drain electrode of a FET, and the high-frequency interior noise is removed by installing a first filter between the pyroelectric element and FET. Therefore, a body sensing signal can be obtained by using only one pyroelectric element.
