New joint DHT11/DHT22 module

@Gordon this does not work for me. I'm using AM2302, ESP8266

{
  "raw": "010000000110011011000000010011000011001­1011",
  "rh": 41.1, "temp": -30.4 }
Temp is -30.4 and RH is 41.1
{ "err": true, "checksumError": false,
  "raw": "",
  "temp": -1, "rh": -1 }

It is getting err: true, if I unplug/replug the data pin from the AM2302 then sometimes it reads like this negative value.

This is the code what i'm using now:

var pin=D2;
var dht = require("https://raw.githubusercontent.c­om/espruino/EspruinoDocs/master/devices/­DHT22.js").connect(pin);

setInterval(function() {
  dht.read(
    function(a){
      console.log(a);
      console.log("Temp is "+a.temp.toString()+
                  " and RH is "+a.rh.toString());
});}, 1000);

Using this is wrong to:

var dht = require("DHT22").connect(pin);
