Probes were constructed to measure non-destructively the moisture content of soil in a pot. The thermal conductivity of the soil was determined using a line-source of heat which yielded measurements ...

[Ryan] designed a PCB that lets you easily take readings from a commercial electrical conductivity probe over I2C. Conductivity measurements are great for measuring the salinity of a solution, which ...

Space probes, gas pipelines, and other applications require an ongoing source of thermoelectric power without direct human maintenance, but current technologies for the corresponding energy conversion ...

Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...
