wired(obniz, {signal [, vcc, gnd]})

// Javascript Example
var sensor = obniz.wired("Keyestudio_MoistureSensor", {signal:0, vcc:1, gnd:2});

onchange = function(value)

callback function called when the value was changed.

// Javascript Example
var sensor = obniz.wired("Keyestudio_MoistureSensor", {signal:0, vcc:1, gnd:2});
sensor.onchange = function(value){
  console.log(value)
};

[await] getHumidityWait()

Measure and get current value once.

// Javascript Example
var sensor = obniz.wired("Keyestudio_MoistureSensor", {signal:0, vcc:1, gnd:2});
var value = await sensor.getHumidityWait();
console.log('Humidity Level:' + value);
