If your data rate is very high, level shifter TXB0104 or TXB0108 may not be
a good option since the level transition is not very smooth. For faster
data rates use open collector buffer(7407 ic) circuit give at

If your sensor pulses don't occur at a very fast rate -- under a few MHz --
the resistor divider should work fine. If they occur at a faster rate, I'd
go with one of the other solutions suggested here.

Alternatively you can buy the TXB0104 as a breakout board here... the only
difference being that the TXB0104 has 4 channels and the TXB0101 has a
single channel:

The Texas Instruments TBX0101 IC should do the trick. The BBB connects to
port A and the speed sensor to Port B. Use the BBBs 3.3V supply to connect
to VccA. Depending on the speed sensor supply I'd regulate that down to +5V
to connect to the VccB pin (can only take up to 5.5V max).

Hi you must use a level translator before interfacing it to BBB
