Issue while creating a temperature monitoring system

When I tried to create a project on temperature monitoring, I faced an issue in the module. I sensed some burning smell from the module then I noticed the wires which were connected to A0 and GND got melted. Can you please tell me the cause of it?

It’s due wrong connection of LMR35,try contacting the bolt service center

I Think, you have connected to 3V pin or any other pins. Check the connection of the LM35 sensor from the BOLT training. And Remember to give the connection when the power supply is OFF.
PIN CONFIGURATION OF LM35 sensor:
pin1=+VCC(5v)
pin2=O/P(A0)
pin3=GND

It got melted because of the short circuit connection. Instead of connecting A0 and Gnd, you might have mistaken the connection with 0 and 3v or 3v and A0.
