Abstract: A wireless mailbox notification system is provided. The system includes a housing structure having a plurality of sensors and a processor therein. The plurality of sensors includes a light sensor and a motion sensor. A wireless transceiver is in operable communication with the plurality of sensors and the processor. The wireless transceiver wirelessly transmits an alert generated by the processor to an application installed on a remote device upon actuation of at least one sensor of the plurality of sensors. In some embodiments, an electronic message is automatically generated and transmitted to a desired recipient, such as via email or text message. A fastener is disposed on the housing, wherein the fastener removably secures the housing to a support surface.
