One of my boards does not like to have the temperature sensor very far from it. When I put the temperature sensor directly on the board, it runs fine for days. When I put the temperature sensor farther away from the board, it reboots or at least the plc code restarts. I've checked and changed the wiring twice. I've used different temp sensors with the same result too. The sensor works fine when it is directly on the board.
I used some cat 5 cable and put the ground and data pin on one pair and the +5 on another wire. The cable is about 15 ft long. The board seems to reboot at random times. I should mention that I also have a humidity sensor on the same cat 5 cable using different pairs going to the same board. Those are the only sensors I have on the board. When I take the temp sensor off or wire it on the board, it runs great. As soon as I put the sensor on the cable, reboots happen.
Has anyone else had this problem? Any ideas on how to remedy this problem would be appreciated.
Thanks
