A sensor cable for measuring moisture inside a grain bin includes a moisture sensor connected to a moisture sensor wire and a pair of holes in the sensor cable. The holes are associated with the moisture sensor to enable the moisture sensor to sense moisture via both of the holes. In one implementation, a moisture sensor is connected to a 3-wire interface having separate power and data wires, thereby increasing the read speed. In one implementation, the moisture sensor is encapsulated within a node that is flush with the sensor cable to minimize load on the sensor cable from the surrounding grain.
