  • Why Choose Us: Are you tired of checking your large mailbox countless times every day? Or maybe you’re worried about someone stealing your delivery? With our mailbox sensor alert you'll be alerted immediately whenever an delivery arrives. Will save you a lot of time.
  • Smart Mailbox Alarm: Whenever the mailbox door is opened more than 45 degrees(Note:the sensor will not be triggered If the mailbox door is not opened more than 45 degrees relative to gravity direction, the A+ below describes how to reduce the trigger angle), it triggers an alarm on the mailbox alert for delivered mail. Even if a mail arrives while you're away, it'll keep flashing to remind you. You press the top of the receiver to turn off the flash.
  • Wide Range Of Uses: this mailbox alarm for delivered mail can be used only for post-mail mailboxes that opens down similar to the mailbox in the picture, or other mail chime only works if the mailbox cover opens downwards ( Note：other horizontally open ones are not supported). The mailbox sensor works well in all seasons and has an operating range of -20 to 50 degrees Celsius.
  • Wide Coverage And Waterproof: Our mailbox sensor alert supports alarms at a maximum distance of 600 ft in the open air (you need to confirm whether it can be triggered before installation), IP55 waterproof level, and is not afraid of rain or snow.
  • Environmental Protection And Long Battery Life -The mailbox sensor installed on the mailbox door has a built-in battery, ultra-low power consumption, and can be triggered more than 5,000 times at most. It can be used for many years, so that you do not need to replace the battery frequently, saving you time. The receiver supports USB power supply or 3 AAA battery power supply, which is efficient and environmentally friendly. (Note: The mailbox receiver can only choose one of the power supply method
  • Easy-to-install Buckle Design - The sliding buckle design allows the receiver to be easily fixed on the wall. First, use expansion screws to fix the base to the wall, then point the USB port toward the direction of the white arrow on the base, and gently click Just push. The mailbox sensor can be easily stuck on the mailbox door with double-sided tape (note: the Up indicator arrow needs to be facing the top of the mailbox door during installation).
  • Adjustable Volume - When you open the mailbox, it will emit a warm yellow light and a gentle reminder. When you get tired of the reminder sounds, you can switch to other reminder sounds, up to three types are supported. The smart mailbox sensor have reserved 5 levels of volume, and the silent mode can prevent your children, elderly and pets from being frightened.
  • [NOTICE] If there are large obstacles between your mailbox and your home, please do not make a purchase. For example, if your mailbox is across the street, when a mail truck stops, it can block the signal because the metal of the truck absorbs electromagnetic waves, resulting in poor signal reception.


Product Description

How to solve the problem that trigger angle is not sensitive enough for very few mailboxes?

Now the trigger angle is 45 degrees

If you have encountered the following problems:

● Only triggers half of the time.

● When a courier delivers a package, it cannot be triggered every time.

Reason: Your mailbox is quite special. The mailbox door may be too large. When the courier opened the mailbox door, the triggering angle did not reach 45 degrees and the alarm could not be triggered.

You can adjust the angle yourself as shown in the figure below.

Bevel and installation steps

Bevel

We have provided a 15 degree bevel in the package, or you can make one yourself using wood.

The bevel is placed under the product

Place the beveled body under the product as shown in the figure.

Install the slider on the mailbox door

mailbox install 03

paying attention to the Up direction of the product. and the position of the bevel. Use double-sided tape to stick the bevel body on the mailbox door as shown in the picture. At this time, the trigger angle will become 30 degrees (45 degrees - 15 degrees). OK, you have accomplished something very interesting. According to the same principle, if you want to use a 25-degree trigger angle, the bevel angle can be 20 degrees (45 degrees-20 degrees). You can customize any angle to suit your mailbox.

How to replace the battery?

The receiver and transmitter are both powered by batteries (the receiver can be powered by USB). If it does not trigger every time after using it for a period of time, it may be that the transmitter is low on power and needs to be replaced.

Battery model: 23A 12V alkaline battery, height x width: 28mm x 10mm.

You can use the screwdriver we provide to open the back cover of the transmitter for replacement.

Mailbox sensor and receiver work very well over our 80 yard distance. (240 feet)Adjustable volume and alerts are acceptable.The unit did come with a plastic wedge to increase the mailbox door sensor opening sensitivity. I wound up using the wedge.The only problem is that our mail person just barely opens the mailbox door (at times) and is not far enough to trigger the sensor. I would like to know if I can get/add a second wedge to use in addition to the first wedge? Or a different wedge that is taller. Otherwise everything is good. Easy installation. Battery life of sensor yet to be determined.UPDATE: Weak point is the 3 extremely small tabs that hold sensor to mounting base. Checked mail yesterday and found sensor on the ground. (Blacktop) sensor mounting tabs have Failed. Sensor is all banged up from falling off of mailbox. Sensor no longer works reliably. Need to replace sensor and mounting plate. HELP.Seller must Not read reviews. Now 5 months later and No response for a replacement sensor. NO seller contact information available. Do Not Buy.

Our mail carrier used to deliver our mail around noon, give or take an hour. Since Covid, the arrival time is all over the clock, many times as late as 9:30 PM, which is ridiculous. I needed a better method of checking my streetside mailbox other than walking out there multiple times at all hours of the day, so I found this nifty alarm. It's been installed for three days now and I can say it works as described.I'm not sure how the remote mailbox unit is powered--the directions don't say anything about a battery and I could not find a way to open the unit. I guess I'll worry about its power if it stops transmitting. Also, the inside unit has all kinds of sounds and tones available. I'm just using the most basic notification. I like that the unit has a bright light up button that comes on when the mailbox door is opened. Definitely get one of these if you need notification of mail arrival.

I bought a well known mail box alarm on Amazon (uses 2 AAA batteries) and the thing receives my neighbor's door opener. It receives the carrier frequency and not a sub carrier which the designer could have easily done by mixing a tone into the main carrier. Some have reported that it picks up stop lights (traffic lights) but is not and picking up door openers. This mail box chime does not do that. It pairs with the receiver making it secure and not receiving other wireless devices.It does have a small problem though as the tilt sensor is soldered on the board (flat) and cannot be tipped like I have done with older less powerful (useless) mailbox chimes. If the tilt sensor had a pig tales soldered on the sensor, the pig tales could be bent and the sensor could be put into the right position. So, without a surface mount soldering iron to desolder the tilt sensor, I had to build a shim to tilt the device at a 30 degree angle. This unit should have been sold with 2 plastic shims one at 15 degrees and one at 30 degrees. Both shims should be stackable to make 45 degrees. So, hopefully the designer reads this and has some company make some plastic shims for the mailbox unit.As far as range, I have it in a steal box about 115 feet away from the receiver and works just fine. The signal goes through the box, through the mail truck and back inside the house. So far… so good.As far as the transmitter battery, it is a 12 volt A23 battery and I like it better because it make the unit more compact (so do not let the special battery scare you as you can get them and replace it).I like the fact that the receiver came with 3 - 1.5 volt batteries for back up power. The backup power batteries work in parallel and not in series (meaning the backup power is only 1.5 volts and not 4.5 volts). The receiver cannot work on the batteries only and are their only so the unit does not unpair from transmitter. Also, I like the fact it came with a screw driver.ALRIGHT, HOPEFULLY THE DESIGNER IS READING THIS....... UUHHHMMM ATTENTION PLEASE!There are many pictures of people dressed up in black clothes with masks taking mail out of mail boxes on Amazon.Wow, wouldn't it occur to the desiner of these things at what «TIME» of night this would be occuring?There is one thing in common (wrong) with all of them unless it is app based. The clock is missing! Where is the clock? The designer can easily grab a cheap dollar clock (with an accurate crystal for timing) and have the display freeze when it receives the signal. The display can have a separate reset button as well to unfreeze the display back to normal time. It can be a cheap 12 hour clock (no AM/PM) as mail is delivered only in the day.SO VERSION 2.0, 3.0, 4.0000, 5.0001234 OR WHAT FRICKEN EVER VERSION YOUR ON, GARB A CHEAP CLOCK (OFF THE SHELF) AND SHOVE THE DAM THING IN THERE!!!!!Who is going to sit up all night! Man think a little bit and think it through. Think what you are posting! Where is the clock?

I licke the voice and light notification. This is my second one. First one died after a few months when the sender failed. Bought a different brand which turned out to be a pile of junk from the beginning. Hoping this one will give good service.
