Hello there,
I have only a very short experience with the sensor but here is what I can say after just one week of usage.
First of all, many thanks for having accepted producing a 0->3v output version. This is the one I use.
I experimented quite a lot with the sensor before actually using it in real conditions and I noticed that it returns very consistent, repeatable results. It has an excellent precision, returning results that you can follow down to the level of 0.01v
My other good surprise is that it has an excellent isolation to the unwanted influence of its surroundings. Sometimes, in this kind of sensors, just approaching your hand to the cable will deeply influence the reading. Not in this case, well done !
All in all, you produced a great little sensor that will find usage in many applications.
There are only two things that would worry me for some time.
First is: will these great performances deteriorate in time or not. I was using an other capacitive sensor and rughly after 2 years the readings were not consistent any more. I guess time will say...
Second is: I hope you will be successful enough to keep producing these. I would hate having to go back to the "other" brand :-)
I want to congratulate you for this achievement. I will keep experimenting with the sensors and buy some more in the future.
Best regards
Edit: I forgot to mention that another strong point of the sensor is its very good temperature stability.
