----- Begin Included Message ----- From: Gerry Smith Subject: Detecting temperature at a point I'm trying to use the PIC processors to detect temperature at a point. Unlike area or room thermometers, I want to take the temperature a spefic point (eg. water or body temperature). Would anyone know of any sensors that would be suited for this? I have thought of themiresistors and temperature ICs. Are there anymore or better ones? If not, which is better? Thanks in advance. ----- End Included Message ----- The devices you mentioned really only take temps at the point where the sensor is, not of an area. You might try attaching your device directly to the object you want to monitor, and insulate from heat coming from other directions to get better readings. If there are more (cheap?) sensors, I am sure several of us are interested!
