I am on my senior year in college taking electronics engineering and currently working on a project that is a trash bin only taking in plastic bottles and giving incentives to the user depending on the properties of the deposited plastic bottle. I have an idea on how to detect the plastic bottle and measure the volume of the plastic bottle using distance measurement techniques. I wanted to also measure the wall thickness because this will determine the sturdiness of the bottle as it will be used for recycling. Is there a component that can measure the wall thickness of a plastic bottle that can be connected to an MCU? Thanks!
