Prototype Optical Bee Counter

This is a single gate optical bee counter using an integrated infrared LED and photo-diode optical detector.
Two sensors are mounted face to face in front of the hive to be able to detect and count incoming versus outgoing bees.
The sensors are available in lots of 10 for about $10.
The HY810H datasheet is available here.[1] Experimental code to count bees is available from hivetool

Now what's needed is a 32 gate (16 slot) custom circuit board with a serial multiplexer and glue electronics.
Similar work has been done using discrete components sensing reflection instead of beam break.[2]
