I got a PIR movement sensor in my hallway to switch the light on automatically. The sensor steers a relay which shorts the light switch. The problem: The relay consumes way too much power, because this thing runs on batteries. I want to replace it with MOSFETs.
RESTRICTIONS:
- I do not have any P-MOSFETs, only N-type ones
- I have only access to both ends of the light switch, nothing besides it, so no neutral wire and no ground of the housevoltage.
- The maximum voltage, the batteries can deliver is 30V (I am using a boost conv.)
Thanks for your help
