I thought maybe you had to design a circuit.scorpioz said:About using the stud sensor, on the page it takes it just says that it use a small radar to sens the different capacitances and therefore when stud is found the capacitance changes. Why did you say will the teacher allow it or not ? I don't see anything that he can object to ?
The L4620 is an integrated circuit, designed for the liquid level control in automotive applications. The liquid level is indicated by an attenuation between transmitted and received signal across a sensor tip in the liquid.
Before you say something like that, maybe you should read the post just prior to yours. It says...justDIY said:Please, go back to the drawing board and come up with a real solution ...
JBscorpioz said:... just to update you, we got the following IC to work perfectly for our needs.
scorpioz said:However this was objected to by the teacher on the grounds that some beverages may not conduct ? / It might not be FDA approved to pass current through the beverage.
The idea i have used right now is to use two contact and have a floating steel ball, and when it comes down as liquid flow it connects the two contacts and current flows...(again i will hv to defend that it is safe to do so)
