IOShield DetectorFrom SPCoast[edit] IOShield 6-pin RJ11 Block Occupancy DetectorThe schematics and PCB layouts shown here were created using the free tools provided by Eagle CAD. I get the boards fabricated at Seeed Studios. Now that I am playing with Arduino based control points, it makes sense to use occupancy detectors that can be connected directly to IOShields. 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] Main Board
