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
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.
