I have a couple of LM335 that I have tried to use with the miniboard. The
numbers I get when converted to Fahrenheit, do not accurately represent the room
temperature. The docs mention using a 10K pot to calibrate the sensor. I have
not yet tried this, but it is my next step. The Robot Bonanza book has a couple
of circuits that use this sensor. I have not tried either circuit from the book.
I do have a handyboard, but I have not tried the sensor with it, but the results
should be that same with either board. They both use the 47K pull up resistor.

| Hi, Has someone tried to connect a LM35 temperature sensor to an analog input in the HB, I have had no luck with it, I have plugged it directly to the input and think that maybe is the 47K pull-up resistor the cause of the problem. Thank You José (...) (25 years ago, 26-Jun-99, to lugnet.robotics.handyboard)
