Hello, I run a fundraising effort in the area and am wanting to find a way of getting an estimate of how many donations are made in the money collectors, allowing me to determine average donation amounts. I'm not interested in somehow counting the money, but rather detecting how many times change or bills would pass through the slot.
These collectors are similar to a Salvation Army collection bucket, to give you an idea. It would need a ten second delay before counting a new donation to allow for people putting multiple bills or coins in. The counter would need to be reset each day, either automatically or with a button; the ultimate, if achievable for under $100, would be a memory that could give an hourly breakdown and up to a 90 day history that could be exported to a spreadsheet.
The slot the money passes through measures a half inch wide and three inches long, and this device would need installed on the inside of the collection bin to be protected from the elements.
Is this possible? Is there an existing project that could be adapted? Thank you in advance.
