A remote sensing device, system and method is described. The remote sensing device includes an enclosure, a smartphone, and a microcontroller. The smartphone is fixedly coupled to the enclosure. The microcontroller is communicatively coupled to the smartphone. The microcontroller includes a power management module, a controller, and a wireless sensor network. The power management module is electrically coupled to an auxiliary battery that powers the smartphone. The controller is communicatively coupled to smartphone and the controller controls the power management module. The wireless sensor network includes a wireless communication interface that is different from the smartphone wireless communication interface. The remote sensing system includes a remote sensing component, a network module such as a web application server, and a database. The network module is communicatively coupled to the wide area network and receives sensor signal output and a timestamp from the smartphone. The database logs the sensor signal output communicated by the smartphone.
