What is the MINIMUM detection range it can be set to?

That's gonna be hit and miss. Turn off the water and listen for the internal valve to "click" as you approach and adjust accordingly. If you don't already have the unit, that will be tough.

Based on my experience, if a system won't detect at 850, then it won't at 940. Cameras and cell phones must have night-vision capability or infrared sensors in order to detect light beyond 850nm. Expensive night googles should be able to see in the IR wavelength, but a search to make sure your devices are capable of the 940nm range is recommended. 940 is often more desirable because it gives off very little visible light and is therefore extremely hard to detect.

We are using the sensor at the front door and do not want everyone on the sidewalk (40 feet away) to turn-on the porch light. We know that when set to minimum it is 20 feet, but we do not know the range of maximum setting.

about 10 m at the out most distance from the sensor. however angle of the sensor and others can reduce the range

Yes but I do not recomend buying do to the large number of false alarms even after adjusting to the lowest sensitivity. Do not buy this detector for outdoor or driveway alarm.

Yes, it can. There's no minimum range. I pair it with the "leave it" command so that if the dog is after something something he shouldn't be he gets a first warning to "leave it" and if he doesn't listen, I press the button and repeat the "LEAVE IT" while holding the button until he leaves it alone. Try a webcam if you want to be able to be out of the room and teach the dog that even if you're not there, the food is to be left alone.

Depending on the location of the camera, I have gotten between 60 and 90 feet for the motion detector to activate. The quality of daylight pictures is very good and the night quality is good as well.

The activation range of these sensors is limited, four to five feet. I have one in my garage by a window in the case of someone breaking and entering through this window. It sits on a shelf facing the window which is fully covered by drapes. The distance between the sensor and the drapes is under three feet. Anyone entering thru this side window will activate this alarm. I tried mounting it high on a wall about seven feet away from the window to prevent an intruder from disabling it. The alarm would not activate at that distance. I ran everything in front of it short of an Elephant, this gizmo would not not go into alarm mode. This is why I had to place it on a lower shelf facing the window. I don't believe the flaps on your entry will set them off if they are at least fout feet away, at the same token an intruder will have to pass within the three to four foot range to activate them, which gives the intruder the opportunity to grab and deactivate them. The y have a very limited range, certainly less tha advertised.

Most consumer-grade CO detectors can detect and display down to 11 ppm. You'll only see this if you push the peak level button. The Defender CA6150 will show ambient level down to 10 ppm with the push of a button.

That's a two fold answer. It will see the bug if in plan sight but is covert but will need to be powered on to detect it. All detectors only detect the frequency they emit. Hope that helps...

Range and sensitivity depends on many things, the most prominent being the total RF power, orientation and the sensitivity of tags. Having said that, this device operates at very low power and for most tags that would be read from 6-8 feet on a regular RFID reader, this device will read them in less than 1 feet. With a less sensitive tag, you can expect the range to be a few inches.

"ISO sensitivity can be set from 3 to 8000 in third-stop increments" (http://www.sekonic.com/products/l-308s/features.aspx)

In my experience the maximum range is about 35 feet from any sensor. Where I live is basically all cement, i would not really know what would be its maximum range but I would guess is something from 20 to 40 feet. My maximum range is 30 feet and I really tested it while I was installing my equipment.

I believe that the range is approx. 12-15 feet. After that the light starts to dim. But for the price of the 2 units, I don't see where you have much to lose.

I have the sensor nailed to a tree about three feet off the ground. It is very sensitive. I think installed at an angle above the garage would work. The receiver in the house works very well and beeps three times everytime something passes the sensor, could be a car, animal, or garbage man. Do not put the receiver near metal like a microwave it seems to block the radio waves. Also when the transmitter is rained on sometimes you get false readings. I put a plastic shroud over the top made from a yogurt container. Overall I am very pleased with the product and for the price it is a very good value. I highly recommend this product.

I think the beam will only shoot out about 30 feet to detect something. Ours is transmitting 700 feet at our house with no problems at all.

I own this alert. The range is fairly good and yes accuracy within a couple feet. Honestly I wouldn't buy this model again. Way too many false alerts, especially if there's a slight breeze.
