FAHRENHEIT TEMPERATURE SENSOR

just the thing for remote air temperature sensing.
put it at the end of some thin 3 conductor wire (2 pair phone cord) attach a 9v battery and voltmeter, and you are done!

As another customer already noticed, some LM34s seem to be actually mislabeled LM35 which produce an output proportional to the temperature in degrees Celsius. Eight of ten sensors I ordered were of that kind. Check your order. EDITORS NOTE: We did receive a shippment of LM34 which appeared to have some mismarked. They have been replaced with the proper part.

I recently purchased some of these for a project. The first one did not read correctly so I tried another and another. A few of them do read very accurately. I have determined that the rest of them are mis-marked LM35's and are reading celsius very accurately. Great price if you can use them anyway.

I'm using this to activate a fan that cools an audio amp I have in the garage. This thing works great.

Bought this to mess around with and i hooked the supply up wrong and almost cooked it but its still working fine. nice and sturdy for the new people out there. also its very accurate from what i can tell.(compared to kitchen thermo and a thermostat i have around here)
