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.
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 element with Fet in source follower connection.
LHi 778 detector is available in TO-5 housing with standard infrared filter. It provides high responsivity with excellent common mode performance (match) and low noise at steady state and temperature changes..
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
