Mainboard and Current sense remote
[edit] Introduction
Now that I am playing with Arduino based control points, it makes sense to use occupancy detectors that can be connected directly to IOShields.
The schematics and PCB layouts shown here were created using the free tools provided by Eagle CAD. I get the boards fabricated at Seeed Studios.
[edit] Features
- Connects to IOShield
- 4 supports remote detectors, either IR or Current based

[edit] Specification
This version is based on Rob Paisley's 555-based detector, which is simpler than Chubb's DCCOD, but lacks the easy sensitivity adjustment that Chubb's design provides.
[edit] Communication Protocol
Uses one nibble (4 bits) of an 8-bit IOShield port:
Bit 1 : Block 1 detection
Bit 2 : Block 2 detection
Bit 3 : Block 3 detection
Bit 4 : Block 4 detection
[edit] Programming
See IOShield_Code
