Pyroelectric detector LHI878 Dual element configuration including FET and optical window
Specifaction

TO-5 housing 
Competitive cost version
Designed for motion control
 

Working Principle 

Pyroelectric infrared sensor would change charge when radiant energy changes. The effect can be used in detecting the change of infrared radiant.The sensors apply to human motion detector,passive infrared burglar alarm and automatic light switch. Based on the same theory, the pyroelectric infrared sensor applies to gas detection with infrared absorption.

Feature
1. Low noise, high detection
2. Excellent common mode balance- dual elements
3. To-39, To-5 encapsulation
4. Apply to both narrow and broad band filters
5. Signal channel or double channels pattern
6. Dual pattern apply to burglar alarm

Typical  Application 
1. Passive infrared burglar alarm: strong anti-interference for strong with light and electromagnetic radiation
2. Human motion detector 
3. Human motion detector of ceiling 
4. Gas analysis
5. Non-contact infrared measurement
