Arduino and an LM34 temperature sensor
Posted By azog on July 30, 2009
Ok, so this is nothing that hasn’t been done before. But I’ve been working on another project, and it is just driving me nuts, so I need to take a break from it, and do something else. Maybe not “simple”, but “achievable!”
I ordered some LM34 temperature sensors to play with, and threw together an Arduino sketch to display them temp. on a multiplexed LED.
I know the picture isn’t very good, but I think you can see the temperature sensor on the right. Don’t know how “accurate” it is. “Accurate” in quotes, because the manufacture claims accuracy, but the environment may not be beneficial. I wonder how much heat is being generated by the Arduino itself? Is it affecting the temperature?
But if you just so happen to be interested, here is the sketch.
