 		 #186743 - counting objects inserted in tube
For my project I need to count number of objects inserted in 100mm diameter plastic tube. At the bottom of the tube is waste container. What type of sensor I can use for this job? I am thinking about photoelectic sensors, but is there some cheaper alternative? Photo diodes array? Ultrasound?

Thanks in advance for any information.
