Abstract
This paper reports the fabrication and system design of a low cost charcoal based moisture sensor of dimension 1 cm × 1 cm × 260 μm. Seven different samples were prepared and calibrated for 25 μL of water. The sensitivities are reported for the different samples. It has been discovered that the final node voltage (post-exposure to moisture) depends on the initial node voltage linearly when the experimental data points are fitted. A ratio in the range 1.16–1.27 is obtained while calibrating for the presence of 25 μL of moisture.
