Intel Edison + Grove - Moisture Sensor

Using Johnny-Five with Grove's Moisture component on the Intel Edison Arduino Breakout. This shield and component will work with any Arduino pin-out compatible hardware platform.

Run this example from the command line with:

node eg/grove-moisture-edison.js

var five = require("johnny-five");
var Edison = require("edison-io");
var board = new five.Board({
  io: new Edison()
});

board.on("ready", function() {

  // Plug the Moisture module into the
  // Grove Shield's A0 jack
  var moisture = new five.Sensor("A0");

  // Plug the Relay module into the
  // Grove Shield's D6 jack.
  var relay = new five.Relay(6);

  moisture.scale(0, 100).on("change", function() {
    // 0 - Dry
    // 50 - Wet
    if (this.value < 20) {
      if (!relay.isOn) {
        // Turn on the water pump!
        relay.on();
      }
    } else {
      relay.off();
    }
  });
});
