So I have an alarm system on my house which has open/close type sensors on each window. Have had it for about 4 or 5 years now. Over those years I’ve had one window sensor that really likes to go through batteries compared to the others. I have to change the battery every 2-3 months whereas the other 10+ sensors have never needed to be changed. It’s annoying because it always triggers the low battery warning in the middle of the night.
Alarm company can look at it but it’s during the day so I’d have to take time off work, pay for inspection/parts/etc. so I’ve basically been lazy about it and just dealt with it since it happens so infrequently.
And then about a month ago I got to thinking. That particular sensor is right next to my trainer, like within 3 feet. So I think the big magnetic resistance unit inside the trainer is causing the battery drain. In this time I had an original Kickr and about 2 years ago switched to a Saris H3 so I don’t think it’s specific to my current trainer.
So I guess I’m hoping there is some kind of electrical engineer on here that might see this and have a suggestion for some type of shield I can build for the sensor to test out. Or any other ideas.
Note, I could rearrange the room to get the trainer farther away but would really rather not as I have it set up exactly how I want it.
