D203S
pyroelectric infrared sensor
The sensitivity balance of dual element sensor is calculated through testing the sensitivity
(single signal output voltage) of each element and using the following formula:
Balance = |VA-VB|/(VA+VB) ×100%
VA = Sensitivity of side A ( mVp-p )
VB = Sensitivity of side B ( mVp-p )
D203S Typical Application
D203S Spectral Response of Window Materials
Notice:
The above curve is the typical figure of 5.5μm pass IR filter, the curve is the average value of IR
transmittance, the window’s substrate is vacuum-coated with semiconductor material.
