Hardware hacker Raj wanted to expand the functionality of his multimeter, so he hardwired a temperature sensor to it. When building new circuits, measuring heat tolerance can be important, and this hack makes it easy to do. Using an LM35 temperature sensor, all he has to do is set the multimeter to 200mV and slide a switch at the top. His extensive documentation can be found here if you’d like to do it yourself.
