David , i am facing a problem with my project , i want to connect the TX ( DS18B20 + Arduini uno + NRF24L01 ) with the RX ( arduino uno + 16*2 LCD ) , i want o send he temp data from the tx to the rx

I actually used the DS18B20 before in a school weather balloon. I was using PICAXE but it was really simple to use. I don't know much about components but I did think this was a good one.

Hello there, Super stuff, nice presentation. Far from not very interesting, it's just up my street. I'm building up a network of sensors with a view to improving my house energy efficiency - it's a mix of utility meter monitoring, XBee's and active control of room temperatures etc. Some of it is still on commercial stuff like USB temperature loggers, but involves climbing ladders. I will use your code to get going as I'm too old to be a good programmer and breaking pelvis after unplanned exit from loft tells me there's a better way. Thanks again

Thank you David, great video. I am doing a similar project, but am looking to get data from eight different temp sensors. I am using the DS18B20 sensors as well. Any recommendations?
@DavidWatts10 жыл бұрын
No real advice needed, each sensor can have a unique address so you are pretty much set. I would really like to see your setup when it is done, I haven't tried reading from multiple locations before.

bee Hive Hi, I am using an older version than you it seems. I hadn't checked in a while. I am using 1.0.5 so that could well be the reason. I will look at updating it. Use the SD-->Datalogger example in your version of Arduino IDE and copy out the appropriate code for initialising and writing.

You just change the files extension from txt to csv on your computer, or set it as csv in your code. The file is encoded as a CSV as it is created, I had it set to txt just so I could open it up in notepad by default. CSV stands for comma-separated values which is how this file is encoded.

Great project, thanks for sharing. I am curious as to why you used an Ethernet shield which was hogging all your pins, was it just to make use of the on board sd card? If so, surely you could have used an Arduino data logging shield instead, cheap as chips and not as pin hungry :).

Hi Mate, the best thing you can do is to add some serial output statements in the 'writeDataToCard' function to see if it is triggering. It records the temperature data every minute so you may want to decrease that for testing.
