The comparison of other models of floor material recognition sensor/transducer:
Product Output Type PCBA embedded Algorism Pre-installed Remark
HT-300PLT1612 Analog signal Transducer NO NO Cheapest, R&D in algorism needed
HT-300PLT-A Analog signal Sensor YES NO Cheaper, Signal amplified and filtered
R&D in algorism needed
HT-300PLT-M Digital signal
(COM) Sensor YES YES Time-saving in algorism, directly set up the value for different floor materials to be able to differentiate
HT-300PLT-MIR Digital signal
(COM+I/O) Sensor YES YES Time-saving in algorism, the default mode is I/O, directly outputting the result for either hard or soft floor type, it can be switched to COM mode to set up threshold value for more floor material detection
