Data read error

Open miguepoloc opened this issue 4 years ago • 1 comments

Hello, I am trying to read the data from a LUFFT 600 weather station or a Hydrolab DS5x probe but I have been able, even if I connect the SDI-12 data pin to any of the pins of the arduino it does not recognize it. How much I achieved was what is sampled in the image and nothing else. Using an OTT datalogger if it was possible to observe the data. image

What type of Arduino are you using? Are you using a level-shifter of any kind? SDI-12 standard is 12V, but some instruments use other voltages. Some sensors may also need extra "wake-up" time before responding to commands. You add that by adding the time as an extra argument on the sendCommand function; ie, sendCommand("1M!",100).
