does it have auto sensor so it turns off when not in use?

Yes--it has an auto motion sensor, but I prefer the timer--I set it to go on at 7 AM and off at 11 PM and it works beautifully!

Yes...It has a timer setting for staying on 30 min, 1hr, etc. However, it has a built in motion sensor, so if there is movement in the room the device begin to display.

No auto shut-off but draws very little power when not in operation. I leave mine on all the time.

No and no need to. It will be auto switch off when no activity detected for a while. Rechargeable batteries are built in and consume little power usually.

No. There is no on/off switch on the sensor itself. If you want that function, you should wire it up through a wall switch or circuit breaker.

Yes, you disable the sensor totally and just use it manually by tapping it on or off.

Unfortunately it does not. It has to be manually shut off when you are ready.

Yes, it automatically turns off after between 15 and 60 minutes while on battery if there's no activity, depending on the situation.

It does have auto shut off. However the one I have has never shut off in the process of me weighing items. It takes about a minute of inactivity for that to occur.

I assume you are refering to the "automatic signal sensing" feature, or better called "auto on/off". The answer is yes! It automaticaly turns itself on when when you begin listening to music (signal sensing), then turns itself off if no music is playing (does not sense a signal). It's a great feature. And a great subwoofer!

Yes, it has a sensor. The sensor is attached to a wire, which is plugged into the unit. The sensor is external, but I am not aware of add-on sensors that are internal, being available.

Yes, once the sensor knows it is dark - it becomes active. The unit stays off during daylight.

Yes, it does. Though I wouldn't leave it unattended and trust to a timer for shut-off.

No - no auto - on feature. It only turns off automatically (8hrs?) and the timer isn't adjustable.

Yes, manual ON (with switch). Sensor will turn lights OFF after no motion time out (adjustable).

I do not think it has auto shut off. It mentions nothing of it on the box or in the instructions.

There is no sensor, it is on until you turn it off. I usually let mine run al the time.
