Hello,
We are doing project on sensors. we are using following sensors in the project HSDL300 and TFDU400. Please give us the details about the sensors usage and frequency used.
Thanking you

These are transceiver modules you need not to worry about operating frequency. It will work with IRDA without any problem. or maybe i am not able to understand what frequency range you are talking about.

Hello Ajay...
Thanks.... we have one more IC GP2D150A... do we need to connect any external hardware for interfacing with 89c52

well u see the output high varies nad max is 3 volts...
if interfacing to 52....
1) u can pull up the input to 5 volts.. using 5k-10k resistor..
:-) 2) get the data on to an adc and read the input voltage fix a range for input high...

just hope the first solution works...
