Short answer is yes. The output is a transistor with a 30K pullup. It should
remain well within spec with 3 additional identical devices plus the current
sourced from the Robot Controller. So you should be able to have a total
of 4 sensors on one input. (You could probably have several more but then
you will be outside the 250mV max output low voltage specification.
Beware, however, that you be subject to interference from any sensor
which may prevent your desired signal from getting through. An interfering
signal on the same carrier frequency being received from any of the sensors
will interface will all sensors.
A more robust approach would be to use separate interrupts for multiple sensors
f you have the available interrupts (from 3 to 6). This way, an interfering signal being received from one sensor will not mess up the signal
being received at the other sensor. You will need to modify the code to
share a timer.
