IR Detector for Mid Range Proximity Sensor
22531-1
DESCRIPTION
The TSSP57P38 is a compact infrared detector module for
proximity sensing application. It receives 38 kHz modulated
signals and has a peak sensitivity of 940 nm.
The length of the detector's output pulse varies in proportion
to the amount of light reflected from the object being
detected.
