The sensor evaluates the time required by the AGC to suppress a quasi continuous signal. The time required to suppress a continuous signal is longer when the signal is strong than when the signal is weak. The result is an output pulse length which corresponds to the distance of an object from the sensor. This kind of analog information can be evaluated by a microcontroller. The absolute amount of reflected light depends on the infrared reflectivity of the object and is not evaluated. Only changes in the amount of reflected light, and therefore changes in the pulse width can be evaluated with accuracy. Example of a signal pattern: trepeat = 500 ms tpi = 120 ms, 38 kHz Optical signal Response of the TSSP4P38 (strong reflection) Response of the TSSP4P38 (weak reflection) Example for a sensor hardware: IR detector IR emitter Separation to avoid crosstalk by stray light inside the housing There should be no common window in front of the emitter and detector in order to avoid crosstalk by guided light through the window. The logarithmic characteristic of the AGC in the TSSP4P38 results in an almost linear relationship between distance and pulse width. Ambient light has also some impact to the pulse width of this kind of sensor, making the pulse shorter.
