Security alarm use Dual Element Motion PIR Sensor D204B PIR motion detector sensor
D204B large window hunting machine dedicated infrared probe
Brief Introduction:
Anti-Jamming Dual Element Pyroelectric Infrared Radial Sensor
The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature. Dual compensated sensing elements are applied to suppress the interference resulting from temperature variation with the EMI components.As a result, the operating stability of the sensor is greatly improved. Our products can be used world wide for many applications. Such as in security systems, burglar alarms, visitor acknowledgement, light switch control and intellectualized toy, etc
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.
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
