All-Purpose Dual Element Pyroelectric Infrared Radial Sensor D204S
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. As a result, the operating stability of the sensor is greatly improved Our products can be used in many applications.

Replacement of cds
The gb5a series is a low cost visible light sensor, with a
Current output which is directly proportional to the light
Level. It has a built in optical filter to provide a
Response which is close to the human eye, or f¼photopicf¼.
The output current can be converted to a voltage by
Connecting it in series with a resistor. The dynamic range
Is determined by the external resistor and power supply
(10k and 5v gives a range of 0 up to 250 lux, but this can
Be over 900 lux with a 1k resistor). The internal dark
Current cancellation enables high accuracy over the full
Temperature range, even at low light levels.
Features
Near human eye photopic response
High ir rejection +c integrated optical filter
Current output highly linear vs light level
Temperature stable
Integrated high gain photocurrent amplifier
Darkcurrent cancellation
Applications
Dawn/dusk sensing
Night view surveillance camera
Display backlighting in laptops, mobile phones, lcd tvs
