With only one sensor how does it know when to turn off?

I believe that the way this one works is by sensing the presence of the minute electrical current or the lack thereof. The sensor must be set so that the pump runs at least 10 seconds. I am assuming that is enough time for the pump to discharge enough water and lower the level of the water in the pump sufficiently to allow the sensor to /not/ sense a current and therefore stop activating.

The switch monitors the motor current and looks for a drop in amps which comes when the pump transitions from pumping water to starting to draw in some air. Please let me know if you have any other questions I can answer for you.

I believe it monitors the current consumption of the pump. When the pump isn't pumping water, the current is reduced. There's also some timers, the timer duration adapts over time based on the current consumption.

I believe it senses a different electrical from the motor when the pump begins to pull air when it empties the tank. I had my doubts when I bought it, but it always shuts off when it should.

If it was powered by regular power it might have that option, but since it's battery powered once the sensors realize it's night it automatically turns on when movement is detected. No need to mess with any switches.

There is only one sensor and it is inside the unit. I don't think this is meant to be outside, it mounts on the wall in the drywall. Whatever is wired to it will turn on when the set humidity is high enough and off when the humidity level drops to the set humidity.

It does announce the zone that in alarm, but does not identify individual sensor, unless you keep each zone only one sensor.

According to the manufacturer supplied instructions under "Mode and Reset", press the mode button twice to turn the Smart Sensor on or off

Yes. I don't know of a way to hook up more than one sensor. Works well though.

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

The sensor turns on/off what ever electrical load is connected to it. Check the amperage rating. like 15 amps or 20 amps; and that is the limit for one sensor. check the amperage draw for the decorate lights (will be somewhere on it)

No, there is one alarm that goes off if the chair or bed sensor is triggered. You do not have to tell this alarm which sensor to monitor, it works when either one loses pressure at all times. You have to turn the alarm off and reset it when it goes off. This alarm can be put in one place in the home, or carried with you - it is the size of a small book. Sometimes I would take it outside if I had to do some work out there. This was truly lifesaving for my mother. I would just run to her room and make sure she did not fall (she has dementia and falling had become a problem.) I purchased mine through Kerr Medical and they were extremely helpful, I recommend them. No, there is one alarm that goes off if the chair or bed sensor is triggered.

I think it is 15 seconds to 2 minutes range of "on" time whenever motion is detected. It stays on if there is continued motion in range of the sensor. It then reverts to the delay setting and shuts off after there is no longer motion.

You can turn the light off manually, through some other scene/timer, or ... if you want the sensor to turn it off without activity, you can create a scene for "no trigger." In other words, when there is "no trigger" of motion, the scene causes something to happen (like turning off the light).

I had the exact same thing happen when I had two. I finally had to turn off my motion sensors and everything else works great. When I had the two sensors turned on, it would also send alert that the garage was opened, but since turning them off, I have not had that issue either. I have not tried (though now I will) to only keep one sensor on while the other remains off.

No, there is no on/off at the sensor. If she tries to take it off or anything like that it will seperate at set it off. It works like a charm. Use the alert channel #4

In this sensor's normal operation, it stays triggered to ON for four minutes before resetting to OFF. If motion is repeatedly detected within 4 minutes, it stays ON. There are three sensitivity settings, at the most sensitive, it will pick up some rather slight movements. If you can set your program to monitor the status of the sensor to turn the light off after the sensor returns to off, that should work. If 4 minutes isn't enough delay, there is also a "Test" mode in this sensor that eliminates the 4 minute reset time and it will continue sending out ON signals every time motion is sensed. You could program in your own time delay in this mode. No clue on how it would affect the battery life.

Yes. Either as independent or slaved. By wiring you can dictate one sensor or both. Instructions are in the package. I have two slaved so either sensor triggers both.

There are three sections. Top in sensor, middle is on button, bottom is off button. Any time it is turned on, it will stay on for 30 minutes unless you hit the off button. You can turn it off at any time with the bottom button, but if the sensor determines that it's too humid or moist in the room, it will turn it back on again. If the moisture level is normal, the on and off work the same as any other on/off switch.

It has a red led light on the top of the unit, it will flash if the sensor was triggered. You reset it by turning it off, then back on.
