user89117: I was attempting one of the project of DHT11 and connected the sensor to my arduino board but when the current passed the sensor became very hot and i think it is damaged now. Please help me

user75248: From how you describe your issue, it sounds like you caused a short circuit. You probably hooked it up wrong. (backwards perhaps?)
If that's the case, you probably fried your sensor and you'll need to get a new one.
Mistakes happen, I've cooked my fair share of electronics. Just try to be careful to wire things up properly.
VCC is positive, GND is ground.
