3.5mm jack pinout?

Gary Oberbrunner

It would be nice to publish the jack pinout, so hackers like me can make their own sensors. (I know there will be a breakout box, but it's easier and cheaper to just connect a sensor to a 3.5mm plug.)

Hey Gary, here is the pin out for the jack.

Tip: 3.3v
Ring1: GND
Ring2: Input from sensor
Sleeve: 1 wire interface, ID for sensor type

How is the ID for a particular board determined? If I wanted to create my own breakout board or moisture sensor how would I do it?

Gary, it's in the works. David's currently working on an update to add vibration support and better battery life, but we should have something up here soon.

I am also curious to learn, how can we create our own breakout boards? I believe, opening that spec would help Twine's adoption.

Is this I2C interface or some other?
Can this accommodate a DHT11 Digital Temperature Humidity Sensor Module ?
