Hi,
WOW 13 posts, and the OP hasn't returned in three days.
- What is the fluid you wish to measure the temperature of?
- Is the fluid under considerable pressure?
- What is the pipe material?
- Do you need the temperature sensor to be in the fluid or on the pipe wall?
- How long would the leads of the sensors be, between the arduino and the sensors?
- Why does the display have to be visible from 15 to 20feet.
- If you could move the display closer, would a smaller display be better.
Now we wait...
Thanks.. Tom..
