Prototype of automatic smart irrigation system

# Record card
59
Description

The prototype uses soil moisture sensors which, through a measurement of dielectric permittivity, estimate the soil moisture based on which irrigation is started through relay-controlled solenoid valve. The system was developed using Open Source technologies. Specifically, for the hardware components, a small sized board computer Raspberry PI 3B + was used together with a 4G LTE Wi-Fi router and a Modbus rs485 / USB converter.

Vacuum Tight Threaded Junction (VTTJ)

# Record card
134
Description

The working principle of VTTJ is extremely simple. Two parts (at least one with tube shape) are screwed one into the other with a mechanical interference that creates a metallic seal. One part presents a cylindrical slot, the other presents a conical ring, whose diameter is slightly larger than the one of the cylindrical slot. When the two parts are screwed together, a plastic deformation occurs in the mechanical interference region.
