Published:2011/4/12 3:41:00 Author:Jessie | Keyword: Pyroelectric infrared, sensor induction control | From:SeekIC

This type of control circuit mainly consists of pyroelectric infrared sensor and amplifying circuit. Pyroelectric infrared sensor isa new type of sensitive components, it is made from high thermoelectric coefficient materialswith impedance matching mosfet and filter piece. Pyroelectric infrared sensor is able to detect infrared ray radiation human issued in contactless manner, and translate it into electrical signal to send out.
