You might want TSSP4038 proximity sensor - it works at 38 kHz too, but seems to me that the data sheet suggests continuous 38 kHz gives a continuous low digital output. Its block diagram shows no AGC block. Having no AGC might stop adaptation. It may be that sensing range is somewhat shorter than those employing the AGC block. | |
