I noticed that MS14A analyse motion each 15 seconds...
Is it  possible to reduce this time that it get a motion each 2 seconds ?

marineau: From looking at the schematic here, MS14A EagleEye motion sensor schematic, it appears the turn-around time for re-triggering is embedded in the PIC Chip. So, no luck changing it.

Thanks Puck, so nothing that I can !
If I pass (quickly:2 seconds) while running vis-a-vis the MS14A between two cycle of detection. It does not detect me!
If I pass (slowly:6 seconds) vis-a-vis the MS14A, so It does detect me !

It really a cheap motion detector !

Does exist another MS*** module that  better that MS14A  ?

The X10 motion sensors detect a temperature change in the infrared range. It takes a certain time to detect this change so that rapid changes like a tree leave moving should not trigger it. That is also why if pointed at a real hot surface it does poorly in detection.

I thought to install 2 or 3 MS14A in my garage... Each module would be set to B1 !
In my sdk program when Event B1 On  would detected , so my program could execute a command B3 On for activate module adjusted to B3.
My program will ignore all event B1 Off but it will turn off B3 Off only 60 minutes after a last event B1 On detected !
