Error analysis of the heat pulse method for measuring soil heat capacity, diffusivity, and conductivity.  1, fiche 1, Anglais, - heat%20pulse%20method

Since the low cost sensor technologies available present several limitations to their inclusion in this system, it was developed and implemented a low cost sensor, as described by Valente et al.(1997), based on the heat-pulse and capacitance methods. In the first method the maximum temperature rise measured at some distance from a line heat source can be used to determine the volumetric heat capacity and hence the water content of a porous media, such as soil. The second method relates the volumetric water content with the capacitance change of a probe, inserted in the soil, according to its dielectric properties. Simultaneous use of both methods improves sensor accuracy, gives built-in fault detection capability, and makes possible self-calibration procedures.  2, fiche 1, Anglais, - heat%20pulse%20method

Simultaneous use of both methods improves sensor accuracy, gives built-in fault detection capability, and makes possible self-calibration procedures.... In a capacitance-based method, the soil moisture can be obtained by measuring the capacitance that varies with the dielectric properties of materials.  1, fiche 2, Anglais, - capacitance%2Dbased%20method
