SPECIFICATIONS
SOIL MOISTURE SENSOR KIT
The two probes are acting as a variable resistor – more water in the soil means better conductivity and results in a lower resistance and a higher SIG out. Your analog readings will vary depending on what voltage you use for Vcc as well as the resolution of your ADC pins.

LED
CIRCUIT CONNECTION
Digital Pin 2 Green wire led
Digital Pin 3 Green wire led
Digital Pin 4 Green wire led
Digital Pin 5 Yellow wire led
Digital Pin 6 Red wire led
Connect the cathode or (-) lead from the LED to the Arduino.
**Here you can put a 1k resistor between anode (+) and the positive rail.
Connect the anode or (+) lead from the LED to the + positive rail of the breadboard.
The moisture has very well defined pin out.
Connect the ground to the ground rail, power to the power rail.
Connect the "AC" Labeled pin on the moisture sensor to analog input 0 pin on the Arduino.
*note, the moisture sensor It has two outs one labeled "AC" and one labeled "DC". The "AC", is a serial signal 0-5 volts that when fully dry it outputs 5 volts, when fully wet, 0 volts. The "DC", is configured with the trim pot and is brought high when the moisture level reaches a desired point.
- Connect the two pins from the Sensor to the two pins on the Amplifier circuit via hook up wires.
- Connect the Vcc from the Amplifier to the 3.3V pin on the Arduino and the Gnd pin to the Gnd pin on the Arduino.
- Now connect the Analog Data Pin to the A0 pin on the Arduino (Since I'm interested in Analog Data).
