I have a cool project I hired someone to do about a year ago, but it never worked entirely. need some help with the programming.
Project: Driveway alert system, looooong driveway.
I have 4 sensor beams shooting across the driveway and they are spaced about 100' apart from each other. Each can provide a NO or NC contact. I have conduit running between all 4 points and was planning to run Ethernet wire between them so all 4 points can come in contact with ONE board, 4 pins on the Moteino board. The board has a LORA radio on it and is transmitting to my Arduino receiver, which is tied to a pi running Domoticz. I hired someone a year ago to build a system for me using 4 transmitters (one for each sensor), but I don't think he knew what he was doing. We got several running temperature/humidity data but, the input pins don’t work like they’re supposed to.
Why 4 sensors on the driveway? Eventually I’ll install my railroad signals and be able to direct one way traffic up and down the driveway! How cool is that!
Help anyone? Happy to compensate for your efforts!```
