Never miss your mail again. The PostBoxPing sensor mounts inside your mailbox and sends you an instant push notification when mail arrives — using long-range LoRaWAN technology that works up to 10km without WiFi at the mailbox.
Powered by a standard 18650 lithium battery that lasts 12+ months, PostBoxPing is the set-and-forget solution for mailbox monitoring. The ultra-low-power magnetic reed sensor detects when your mailbox door opens, wakes the LoRaWAN transmitter for just a few seconds, then goes right back to sleep.
