Such a sensor is evaluating the time required by the AGC to suppress a quasi continuous signal. The time required to suppress such a signal is longer when the signal is strong than when the signal is weak, resulting in a pulse length corresponding 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 much on the environment and is not evaluated. Only sudden changes of the amount of reflected light, and therefore changes in the pulse width, are evaluated using this application. Example of a signal pattern: trepeat = 500 ms tpi = 120 ms, 38 kHz Optical signal Response of the TSSP58P38 (strong reflection) Response of the TSSP58P38 (weak reflection) Example for a sensor hardware: IR Receiver TSSP58P38 Emitter TSAL6200 Separation to avoid crosstalk by stray light inside the housing There should be no common window in front of the emitter and receiver in order to avoid crosstalk by guided light through the window. The logarithmic characteristic of the AGC in the TSSP58P38 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.
