Can you are anything like me, you look forward to the mailbox arriving like a kid nervously waiting for his presents on Christmas Eve. Since the time my mailbox arrives is not always consistent, I checked my mail multiple times a day. To solve this problem, I created a wireless sensor that tells you whether there is mail in the comfort of your own home.

Here’s how it works:

The transmitter will sit under the mailbox and when the door is opened it will send a signal to the receiver telling it the door has opened ( indicating that the mailman has put the mail in). The receiver will then light up a LED indicating that the door has been opened and that’s it!
The Wireless Mail Alert lets you know when mail is delivered eliminating repeat trips out to an empty mailbox. The mailbox sensor is triggered when the mailbox door is opened. The sensor sends a wireless radio signal to the indoor receiver display, operates up to 1000′ (line of sight), which will sound a tone/tune or programmable voice message letting you know the mail has arrived. If the supervised transmitter is removed from the mailbox, stolen, loses signal or battery is low, the receiver will produce a single beep once a minute. Sensor uses one 3 volt lithium battery (included), with an average life of 5 years in normal use.

«I don’t know how far your house is from your mailbox, but my mailbox is approximately 350 feet from the house. It’s tiring at my age to travel back and forth several times a day to see if the mail has arrived. My mail is delivered at various times.
Can you recommend a reliable wireless mailbox alert system alert that will transmit at least 500 feet?
There are pine tree branches hanging down possibly in the line of transmission, but they can be cut.
This unit also has a built in protection feature, if the transmitter is removed, stolen, loses signal or has a low battery, the receiver will generate a consistent beep every minute until acknowledged!
