Hello Shannon,

I implemented the wireless communications using Xbee S2, I do get the data from the sensors using your code but the serial mornitor gives some extra junk data as shown in the attached screen short. I am trying to figure out how to eliminate that, Can you please help.

Thanks

I tried placing an order for the mayfly board on amazone but it looks like they are not available and it says they don’t know when next the board will be available for ordering. Do you have any idea where i could buy the board?
Thanks

I plan on making this project interesting that way I get a better understand on how to work with the Arduino and the SDI12 sensors. I am thinking of wireless transfer of the data using ZigBee, then adding memory card shields on the Arduino to store the collected data locally. So do you have any pointers that could help me achieve these extra features. Thanks

Thanks, I followed all the steps above and connected the sensor to the Arduino and all works great. I can get data from the sensor now. Just a quick question if I want to connect several sensors to the Arduino will the 5V be enough or I will have to use an external power supply making sure both the supply and Arduino have the same ground?.

Thank you so much for the help.

Thanks for the reply, the reason I used an external power supply is because when I connected the sensor wires to the Arduino board, and ran the address change example the sensor couldn’t be found by the code so the code continued searching for a sensor in a continues loop. Let me try every step you have recommended and hopefully I get some data from the sensor.

Thanks

Tried the code again and followed the steps as mentioned above, but can’t still get data from the sensor on the Arduino serial monitor. attached is the section of the code I edited to work just for a single sensor and the connection of the sensor to the board. Please help with what I am doing wrong.

Hello Hicks, tried the code you provided for 2 sensors, and followed the steps but still cant get results on the serial monitor, can you please check the code to see if you can get the results.

Thanks

Thanks for the reply. I tried following the steps as you suggested above, i noticed when i uploaded the address change example onto the arduino board and connected the sensors it ask for new address i input 1 for the first sensor but the address of the sensor still said 0. I continued with the other sensors as you had suggested, but at the end when i ran the sample code you sent i could not get the results. I don’t know exactly what i am doing wrong.
So i went ahead to measure the input voltage at the sensors but noticed it was really low so i am guessing thats where the issue is. Please can you provide me with a diagram on how to connect the few sensors to gather?

Thanks

Hello Hicks,
Thanks for the quick reply, for now i will use a wire nut to join the sensor wires, and i will want to get the samples every 10 minutes. Right now if i can get the results on the serial monitor that will be ok because its just for testing, but latter on i plan on transmitting this data wirelessly to be stored on another arduino, probably the Mayfly.

Thanks

Their endings are bare wires, please can you give me pointers on how to get this sensors working with the arduino, that is what sections of the code do i have to edit?

Thanks
