I need some help in finding a sensor. I want something that will sense when a human body is nearby (in my case when I am sitting on a chair).
I don't need any fancy data reported to the Arduino - pressure, weight, distance, etc - just yes or no if my rear end is within a few inches.
The functions described in the Capacitive Library sound like they fit the bill exactly, but I am hoping to find a pre-made sensor for two reasons:
- This is my first Arduino project and I would rather not get into the wiring, soldering, etc quite yet. I also don't have the soldering equipment, not to mention the fact that components needed usually have to be purchased in quantity and I only need one of each.
- I am hoping to write-up a tutorial and I'd like to make it accessible to others like me who can't wire things together.
I don't mind a little cost (especially if it works straightforwardly), as commercially available alternatives to the device I want to build cost upwards of $100 USD.
