Sensor wire recommendations

What type of sensor wire is recommended?
We recommend using AWG 22 multi stranded copper wire with dual conductors (also known as fire alarm cable). Thicker wire works as well, but is not required for good performance.

What is the maximal length of sensor wire?
Although the electrical characteristics of the sensor and the interface allow for long length, there are some practical considerations for keeping the wires as short as needed. A long wire can pick up interference from local radio stations and induced voltage from lightning during thunderstorms. Although the sensor inputs on the Vinduino station have a protection circuit, nearby lightning strikes may overwhelm the circuit. This risk increases with longer wire lengths. Common sense recommendation is to install the sensors under or close as practical to the sensor station.
