Sensor Junction Box

Assembly

Local box that digitises and aggregates nearby analogue sensors onto the data bus, so thousands of discrete signals do not run end-to-end as individual wires. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

Sensor Junction Box parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Bare PCB 1× Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2 Microcontroller 1× Signal conditioning and digitisation
3 SMD Passive (R/C/L) 400× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
4 Connector 16× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
5 Pressure Sensor 2× Local pressure channels
