More Information
Summary:Each grain bin includes a data collector coupled to multiple capacitive moisture cables, each with multiple sensor nodes spaced along it. Each sensor node includes a pair of longitudinally extending capacitive plates of the capacitive moisture sensor positioned in side-by-side, spaced-apart relationship to form a longitudinally extending gap between the capacitive plates. Positioned within the longitudinal gap between the capacitive plates is a circuit board including a microprocessor, memory, and temperature sensor. An outer housing provides a sealed enclosure that surrounds the circuit board, the capacitive plates, and a longitudinal length of the moisture cable that extends through and seals openings in each longitudinal end of the housing.
