TSSP77P38 Description
The TSSP77P38 is a pact 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.
