1. A soil moisture sensor, comprising:
- a double groove helical structure having grooves and formed from an insulator, the grooves driving the soil moisture sensor into a ground portion perpendicular to a surface of the ground portion;
at least a first electrode and a second electrode formed from one or more metals deposited at least two different locations on the grooves;
a processor for processing a soil moisture measurement signal based on a conductivity between the electrodes; and
a wireless transmitter for transmitting the soil moisture measurement signal to a remote location.
