Alternatively, the conversion circuit provides the measurement as a voltage output. The use of a relatively thin dielectric coating on each of the electrodes increases the capacitance and reduces the soil resistance as a factor in the soil moisture measurement. Based on the cylindrical shape of the...
to 122°F). Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and the smart sensor adapter housing (the portion of the sensor cable that houses the electronics) can be exposed to temperatures up to 70°C (158°F), the soil moisture ...
