I believe the sensor stopped reporting normal values exactly when I restarted the board. I’ll have to check to make sure the sensor connector has a good connection. I believe we’re using the Grove stereo jack adapter board. (I didn’t assemble or program it. I am maintaining it.) I’ve attached a photo of the board. We do not have a celular board set-up yet, we are using the memory card only.
Corrections from above………….
We are using the grove screw terminal board with the bare wires. I checked those connections and I checked all other connections and everything seems to have a good connection. I also checked the sensor in the water and brush it clean with my hand. Still no data coming from the stream. I also checked to see if the wires had been chewed and found them in good condition.
