Honey Bee Counter Circuit

Posted on Feb 6, 2014

Real time clock turns OFF the counter at night for reduced power. When the bee crosses under the LED the light is reflected back to the sensor. (its a photo transistor) and triggers a digital input to the Arduino. (or teensy in my case). I lined up two chips right ne

xt to each other. as the bee goes through the gate if it hits the inside sensor first. its going out. if it hits the outside sensor first its coming in. More on the programming. - per the large schematic below, I used 100k ohm resistors to ground. this increases the sensitivity. If you use a smaller resistor it becomes less sensitive. It is an NPN Phototransistor.
