I need to make a few battery operated garage door tilt sensors.
Are there any considerations on which sensor to choose? I think the new 9-axis sensor could do it, but may be bad on battery life due to idle power usage.
Or I suppose I could just do a contact switch, but I have had bad luck over time with every switch based tilt sensor I’ve made, that is why I was thinking about doing something fully digital. But I guess I need to think through this some more.
