Sensor for Mail-Slot Type Mailbox
Our mailbox is built into the stone exterior of our house. When mail is inserted through an exterior 3” x 10” brass flip-up door, it will drop about two feet through a galvanized liner. On the interior, a small 6” x 10” flip-up door is opened to retrieve the mail.
Since the exterior flip-up door is made of brass, the Sensitive Strips may not be an effective solution. I was thinking of using the Samsung SmartThings Motion Sensor (F-IRM-US-2) placed in the bottom of the galvanized liner. When mail is placed through the flip-up door, the sensor would register movement whether mail remains in the flip-up door or the mail drops to the bottom of the liner.
My wife loves receiving snail mail and checks the mailbox several times a day, typically before mail arrives. Therefore, I would like to set up a SmartApp to send a “You’ve Got Mail” .wav file to my wife’s iPhone. An alternative would be to just push the same message to her iPhone.
Will this sensor respond to limited light? i.e. when the outside flip-up door is opened by the carrier, some light may be available in the bottom.
Will the sensor work if mail doesn’t drop through the liner? i.e. the mail carrier bundles magazines around the mail and places it in the opening of the flip-up door, so nothing will drop through the liner.
Will this sensor work with no light? i.e. in the event mail is delivered on an overcast/cloudy day or after 6:00 PM in winter. I could add a small LED light device adjacent to the sensor.
Will this sensor operate in lower temperatures? We live in climate zone 6, but temperatures seldom drop below 30’F in winter.
Does anyone have experience with this motion sensor or other devices for our type of mailbox?
Thanks in advance…
