Digital PIR Sensor 3Pin 5×3.8mm Pyroelectric Infrared Sensor Dual Element – D203B
Description
The D203B 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.
Features
The junction field effect transistor realizes impedance transformation in the form of source follower
The dual-element compensation structure is adopted to effectively resist the interference of environmental changes, vibration and stray light
