DHT11强尼五人无数据

Question

我想和Johnny Five一起询问Arduino DHT11。我正在将Arduino Uno R3用于带有StandartFirmata.ino的主控制器，将Arduino Nano用于具有dht11_i2c_nano_backpack.ino固件的DHT11背包，并且所有布线都像在the schematic here中一样。

代码如下：

var five = require('johnny-five');
var board = new five.Board({port : "COM5"})

board.on("ready", function() {
 var multi = new five.Multi({
 controller: "DHT11_I2C_NANO_BACKPACK"
});

multi.on("change", function() {
  console.log("Thermometer");
  console.log("  celsius           : ", this.thermometer.celsius);
  console.log("--------------------------------------");

  console.log("Hygrometer");
  console.log("  relative humidity : ", this.hygrometer.relativeHumidity);
  console.log("--------------------------------------");
  });
});

结果如下：

1533923685910 Connected COM5
1533923687598 Repl Initialized

   celsius           :  0

   Hygrometer
   relative humidity :  0
