battery sensor - issues with placing batteries in parallel ?
-
Hello,
I hope to be soon able to build some battery powered sensors, and for one of them, I thought I reuse the enclosure of a cheap battery powered siren (something like this : http://snag.gy/M0jJe.jpg). I would use it as a motion sensor
This item is powered by 4 aaa batteries, and I thought it could be a good idea to put two pairs in parallel as it seems to be a common practice to run with two 1,5v batteries. That way, there would be no need to reduce voltage to 3.3v for the nrf24L01+.
Am I correct or is there something I've overlooked ?
Regards

The siren probably has all four batteries in series, so you would probably have to modify the battery holder to connect two pairs in series.
But yes, since you have the space for four batteries you might as well use that and double the battery life.
