tsop1738

[shubham Trivedi]

hello, i want to interface TSOP1738 sensor to 8051 microcontroller. now the problem is that, as this sensor product active low output while 38 khz pulse is received to this sensor. that means we can only controller signal device through this sensor. is this possible to controller more number device through this sensor by providing different frequency pulse to this tsop1738 ?

its not like that

it will work only at 38 KHz but you can generate different codes and modulate them at 38 KHz

the sensor will only demodulate the codes and furthure it has to be decoded by any decoder chip or micro controller
