Weather Durable Wiring

Using Arduino Project Guidance

You have a few weather and environmental-related issues to guard against:

  1. Ingress of water where the cable is terminated. To prevent this, use waterproof glands where the cable enters the PIR detectors and any junction boxes you have. Feed the cables into the underside of the detectors/junction boxes and/or use drip loops to prevent water running down the cable and into the glands.

  2. Degredation of the cable sheath because of UV light. Use a suitable outdoor cable, or run the cable in conduit.

  3. Rodents attacking the cable (some rodents need to chew on things to prevent their teeth getting too long, and they love wires). Use conduit or steel-armoured cable.
