Can the sensor get wet? Live on south side of a apartment, but our mail box faces the north. Am I correct, the most accurate reading is from North?

Yes. I've had my sensor outside year round, from 90+ to -25. In extreme cold I've noticed a problem that it changes from degrees F to degrees C but other than that the sensor works great.

I would not place a motion sensor 300 yards away from the mailbox to alert you when someone is delivering mail to your box. At 300 yards, the sensor will pick up a lot of other movements - birds, etc... Best to put (screw/tape it down) the sensor inside the mail box. It has been three months, and the batteries in my units are still working good. You question is probably whether the receiver can receive signals from a sensor that is 300 yards away. You will never know until you try it - every situation is a bit different. The signal can be easily blocked by multiple walls, etc... I have tried up to 100' (size of yard) and it still works - 300 yards is very, very long way away.

I have all my sensors inside barns that are 200ft. from my house and it has worked well. Don't know how they would do if they were outside in the weather.

Weather is downloaded from the internet base on the city you provide. There are no sensors outside of your house to read the weather.

I don't know if it should be mounted outside or if the sensor can be placed in water. I've installed mine inside in a temperature and moisture controlled area--with the sensor inside a conventional refrigerator. I suggest you contact Johnson Controls for more information about how to complete your installation.

I would be careful about overloading the sensor. Also, don't run this test in a closed garage, for your own health.

I use this sensor for that. I have it just below the lip of the basin. So far, I haven't had any overflows, but also no false alarms either. I think you want to be able to place the sensor in a position that will not get wet when you use the basin for other things or any splashing from the drain will get it wet.

The sensor has to be wet to energize the circuit. Unfortunately about 18" has to be wet to make it work. I did not have gutters either, and I found that the unit would not work for me. The snow just ripped the sensor wire off the roof. The frozen ice on the sensor does not activate it.

Most definitely. Mine is place next to my mailbox. Its in a covered area. Its also very bright. Great sensor. As soon as i open my front gate, the light turns on.

I put the sensor inside a utility closet at the side of my house. It works great. I would think it would work just fine between a window and screen. Also, there is a round attachment on the back of the sensor that you could put a string around and hang it from that.

Just open the box and quickly remove your mail. I never had problem with rain. Changed batteries 4 times and still the unit worked only "sometimes". Today, FEB 10, the alarm DID NOT go off when the mail was delivered, BUT DID GO OFF when my wife opened the box and took the mail out. What good is that ?

If you have a smart phone, it appears to duplicate those temperatures exactly. Not sure where that data comes from. There is no sensor to place outside though.

James,I need to correct my answer. There is a box that shows the temp, humidity, and wet/dry on an LCD. The sensor is on a 6 foot wire. You could place the sensor in a hidden location (e.g., cabinet) and be able to see the LCD. So there is a visible indicator. In my case, my feet would be wet before I could see the LCD, so the visible display (for me) is worthless. There are devices that produce an audible alarm when water is detected (consider running leads from the test contacts on a smoke alarm), if you are there to monitor the condition.

the short answer is read the manual online and the answer would be no. however it depends. do you plan on using the powered components like temp or light? If so I wouldn't be exposing to the elements. But under some sort of cover as a battery operated motions sensor for example. sure. For example I've tried it as a "you've got snail mail" and had it in the letter box and it works fine.

I had my below ground theatre tested with the mail in it was 18pci/l and thats what the meter read as well. After installing simple crawlspace ventilation (which came back at 40pci/l), 6 months later my long term readings dropped to 1.7ish, the hourly still goes up to about 2.9 in the rain but I think it's accurate enough to be within a1pci/l at the worst.

I'm not sure why they say that. Mine came with an outdoor sensor that sends signals to the inside unit for Temp/humidity. It's white .

Cold is ok but not wet. I'd get outdoor sensors if that is what you need. I put one under an eave on a porch and it is fine.
