  The ability to visually verify some element of a remotely controlled
agricultural automation system through a photograph is valuable in many cases,
not only in the operational phase of the system, but especially in the design
and implementation phases. Owing to the remote location of many of the
application sites, cellular technology is one enabling medium through which
wireless transmission of the photographs could be realized. As data usage is a
concern for systems using cellular technology, MQTT chosen over other protocols
due to its lower message-to-header overhead. This paper outlines the hardware
and firmware design of the LTE Cat-M1 enabled embedded system and the backend
web development of the cloud-based web application to facilitate the receiving
of the photograph. A satisfactory degree of implementation success was achieved
in this project, with deployment to a production environment possible after
further refinements.
