I have extremely limited knowledge when it comes to electronics and this field and need help creating a prototype. I wanna create a tobacco bowl which can keep track of how many times you use it. So the product would be a glass device with a sensor that detects hot ash going through the hole at the bottom of the bowl (ASH ONLY). It's very vital to the item that only the hot ash would get detected and would be connected to a counter. If anyone can give me any knowledge or advice on how to create this particular sensor it would be much appreciated, I'll even pay you! Any questions or comments are very welcomed.
