I have read a few different threads on here and on other site discussing temp sensors, but as I am a complete novice I would like to ask not only a solution but also for some little guidance on what the solution means.
Arduino Uno is my board. Among other things I want to run 2 temperature sensors for measuring temps in 2 different locations.
I want to put the temp sensors on the end of at least 3m of lead length.
Some people have suggested that the temp sensors pick up noise on varying lead lengths and suggest to quieten the noise to put capacitors into the mix.
Can some one explain exactly where I would put the capacitors in (maybe a simple line drawing/schematic)
What would be the best sensor to work on a 3m lead length TMP35,LM35,DS18B20 etc or another type.
If you help, could you also explain a little on what the capacitor does within the above circuit design and what values would do etc
Thank you for helping.
