HOW TO MEASURE TEMPERATURE USING ARDUINO

i want to measure the temperature of water inside a pipe using arduino.How can i do that???

You can connect a simple water temperature sensor inside the pipe ...

Why is your Title SHOUTING at us? It's neither polite nor necessary.

You need to find a temperature sensor that can be placed inside a water pipe and which can be read by an Arduino.

The simple temperature sensors that I know of such as the LM35 or LM335 need to stay dry. Maybe you could make a waterproof housing for one of them?

I submit the first thing you need to consider is if you really need to do that. It is common practice to use a thermowell, particularly with electronic sensors.

The next thing to consider is if you really need to do that. You may find it just as effective, and a hell of a lot easier if you simply hold the sensor on the side of the pipe under an insulating sleeve, and use a thermal paste or silicon. I use both methods and I can't tell the difference. There is likely to be a difference with plastic pipe like Pex, but not with copper.

SHOUTING is not a good idea, people may ignore you.

Worse than shouting is starting a thread, getting a page full of helpful replies, and follow-up questions, but never returning to answer or acknowledge them. Hopefully that will not be the case here.

Ain't that the truth. Happens all the time. Shame.

Oh, forgot to say, my YouTube video #28 shows examples of (multiple) temperature sensing, including a brief mention of a waterproof one (but not one that gets actually inserted into a pipe). If you want it less intrusive you could lay it on the pipe, bonded by heat-sensitive cement and insulated with some good pipe insulation - should be within a degree or two of the actual liquid, I would have thought (after all, my home hot water cylinder has a surface mounted stat on it and it's accurate enough).

Hi
Welcome to the forum.

Can you please read Sticky Topic How to use this forum at the top of the index page.

As has been said, CAPITAL LETTERS infers you are shouting.
Because you are the originator, you can go back and edit the title, please.

This just tells us what you want, not what the conditions are and what you want to do with the temperature.

  • What is the temperature range?
  • What sort of pipe? (metal,plastic etc.)
  • What is the distance between sensor and controller?
  • What do you want to do with the controller when it has measured the temperature.

Thanks.. Tom.. :slight_smile:

Some of us older guys are hard of hearing....

WHY DON'T YOU USE A DS18B20 WATERPROOF TEMP SENSOR ?

OR
PIPE SENSORS

No ?, really ? I don't use my keyboard to shout either.
