產(chǎn)品名稱：LHI778
 
  產(chǎn)品編號：紅外傳感器LHI778
  產(chǎn)品規(guī)格：雙元熱釋電紅外傳感器 8.3*4.2mm 
  產(chǎn)品說明：
  The LHi 778 pyroelectric infrared-detector series are the standard dual element design recommended for all variants of motion control. They include a dual element pyro-electric ceramic with FET in source follower connection. The LHi 778 is available as TO-5 housing with standard infrared filter. It provides for high responsivity with excellent common mode performance （match）. RF improved options are available.

Best choice for human body detector. Highly sensitive to human body while remaining insensitive to ambient temperature change, vibration or optical noise. This is due to the dual configuration which electrically cancels such effects

說明 該傳感器采用熱釋電材料極化隨溫度變化的特性探測紅外輻射，采用雙靈敏元互補方法抑制溫度變化產(chǎn)生的干擾，提高了傳感器的工作穩(wěn)定性。
使用 1、上述特性指標是在源極電阻R2=47KΩ條件下測定的，用戶使用傳感器時，可根據(jù)自己的需要調(diào)整R2的大小。
2、注意靈敏元的位置及視場大小，以便得到*光學設(shè)計。
3、所有電壓信號的測量都是采用峰一峰值定標。平衡度B中的EA和EB分別表示兩個靈敏元的電壓輸出信號的峰一峰值。
4、使用傳感時，管腳的彎曲或焊接部位應離開管腳基部4mm以上。
5、使用傳感器前，應先參考說明書，尤其要防止接錯管腳
