Interfacing with DHT11 temperature + RH sensor

This looks much better:

var dht={};
var watch;
var i=0;
var out=0;
var pstart=0;
var badbits=0;
dht.read = function (a,pin) {
	dht.onreadf=a;
	if (pin===undefined) {pin=C6;}
	i=0;
	out=0;
	badbits=0;
	digitalPulse(pin,1,0.08);
	setTimeout(function() {pinMode(pin,'input_pullup');watch=setWa­tch(function(t) {dht.onwatch(t);},pin,{repeat:true});},0­.07);
	setTimeout(function() {dht.onread(dht.endRead());},50);
}
dht.onread= function(d) {
	if (d.temp==-1) {
		dht.read(dht.onreadf);
	} else {
		dht.onreadf(d);
	}
}
dht.onwatch = function(t) {
	if (t.state) {
		pstart=t.time
	} else {
		var tt=t.time-pstart;
		if (tt < 0.000044) {
			badbits = 1;
		}
		if (badbits) {
			out=(out<<1) | ((tt > 0.000044) && (tt < 0.0001));
		}
		i++;
	}
}
dht.endRead = function() {
	clearWatch(watch);
	if (badbits && i > 32) {
		rh=(out>>(i-10))&0xFF;
		temp=(out>>(i-26))&0xFF;
		return {"temp":temp,"rh":rh};
	} else {
		return {temp:-1,rh:-1};
	}
}

Any other cleanup suggestions?
