DHT22 problem

Found a solution changed 6 to 60 on the outer setInterval of the module

var dpin=B3;
var F;
var H;

function DHT22(pin) {
  this.pin = pin;
}

DHT22.prototype.read = function (cb, n) {
  if (!n) n=10;
  var d = ""; 
  var ht = this;
  pinMode(ht.pin); // set pin state to automatic
  digitalWrite(ht.pin,0);
//  digitalWrite([ht.pin,ht.pin,ht.pin,ht.pin,ht.pin],0x0a);
  this.watch = setWatch(function(t) {
    d+=0|(t.time-t.lastTime>0.00005);
  }, ht.pin, {edge:'falling',repeat:true} );
  setTimeout(function() {pinMode(ht.pin,'input_pullup');},1);
  setTimeout(function() {
    clearWatch(ht.watch);
    delete ht.watch;
    var cks = 

        parseInt(d.substr(2,8),2)+
        parseInt(d.substr(10,8),2)+
        parseInt(d.substr(18,8),2)+
        parseInt(d.substr(26,8),2);
    console.log(n,d.length,cks&0xFF,parseInt(d.substr(34,8),2));
    if (cks&&((cks&0xFF)==parseInt(d.substr(34,8),2))) {
      cb({ 
        raw : d,
        rh : parseInt(d.substr(2,16),2)*0.1,
        temp : parseInt(d.substr(19,15),2)*0.2*(0.5-d[18])
      });
    } else {
      if (n>1) setTimeout(function() {ht.read(cb,--n);},500);
      else cb({err:true, checksumError:cks>0, raw:d, temp:-1, rh:-1});
    }
  },60); //////Changed value to 60 from 6
};

//var dht = require("DHT22").connect(dpin);
var dht=new DHT22(dpin);
setInterval(function () {
  dht.read(function (a) {
 F=(a.temp+40)*9/5-40;
 H=a.rh;
  console.log("Temp is "+F.toString()+" and RH is "+H.toString());
});
//    });
}, 1000);

Sample output Temperature in F.
