[TriEmbed] Low power IR beam sensor

[Chip McClelland]

All,  any ideas on a low power (5mA and 3.3-5V) IR beam sensor (transmitter
and reflector) I could use in an outdoor setting?  Need to count
pedestrians walking on a gravel road and the width - 30' - is too great for
ultrasonic. Ideally, could buy the sensor components directly and integrate
them with my data logger board.

Thanks,

Chip
