    How It Works...
  

*by J***. on Reviewed in the United States 🇺🇸 on April 8, 2015*

This item took me a few minutes to figure out... but I think I like it.Setup:1) You have a 5-wire ribbon... tear it into 2-wire ribbon and a 3-wire ribbon.2) Use the 2-wire ribbon to connect the fork-shaped sensor to the the 2-pin end of the circuit board.3) If you look at the 3-pin end of the circuit board you'll see: VCC (5V in), GND (ground), DO (digital output 0.18V/5.00V), AO (analog output 0.00V-5.00V)4a) If you want to use this as an analog sensor, connect the AO pin to an input on your Arduino. You'll be able to read voltages between 5.00V (totally dry, air gap) and 0.00V (totally wet with no resistance). You'll have to determine what to do at any particular voltage level.4b) If you want to use this as a digital sensor, connect the DO pin to an input on your Arduino. The device will either output 0.18V (wet) or 5.00V (dry). The secret is the potentiometer on the circuit board... you can calibrate when the sensor transitions from wet/dry.Hell, you could even connect both AO & DO to your computer and measure them separately, if you wanted to. I plan on using this to automatically water my plants. I'll use the sensor in digital mode, and use the potentiometer to determine when the sensor will signal to my Arduino to water my plants. Then I can re-calibrate the sensor on each plant separately, whenever I want, without having to touch the code on the Arduino.My only question now is "Will it last outdoors without any weatherproofing on the connectors and circuit board?". The answer is probably "No". So I plan to seal it in hot glue... I just have to figure out how to do that and still be able to access the potentiometer for adjustment.I hope this helps.
