![]() ![]() no soldering, or you will find posts here on how to remove the regulator (and a diode). The circuit for that device is available on the internet and you can actually bypass the regulator just by changing how one of the jumpers are setup, i.e. Although I have not measured how much energy the regulator itself uses, but it may be more that the Motion Sensor itself which only draws 50 micro-amp (50 millionth's of an amp). The IR Motion sensor you are using is actually a 3.3 volt device and has a regulator to drop the 5V input to 3.3v, so it's just a waste to use 5V only to drop it to 3.3v. Because this is a battery powered device, I assume battery life is reasonably important and there are improvements you can make. ![]() Hi, Just a few comments that you may find useful.
