Can the Props A/D conversion be used with a LM35 Temperature sensor?
Thanks.

Micrchip,Linear, and anolog have some options that would be more suitable and a few in PWM output that would obliveate you having to impliment the A2D circuit required on the Prop. You could just use the counters to measure the signal and cooralate the temp from that. I don't know if that PWM version come in a TO-92 die or not but most do.
I found the sensor in a bargain bin, and needed one for a project. Hmm, may have to get something that spits out values on a serial line.

Sorry for the LM35 but i discover rescently ( thanks to this forum and to Brian and Tracy ) the DS18B20 from Dallas. It is a 1_wire device (serial) very easy to interface with the Propeller. Even at long distance, 20M with just 2 resistors and 3 cables, or a simple transistor and 2 cables.
You can find sample to use it in the Object exchange, '1-wire routines'.
Best uses,
