  The constant technological evolution allowed significant advances and
improvements in the processes of industries, mainly in areas that demand
greater control and environmental air efficiency. In this way, Embedded Systems
allows the development of products and services that aim to solve or propose
solutions in these industrial environments. This article presents the
development of an Embedded System with a Programmable Logic Controller (PLC)
and Arduino for industrial air dehumidifier, which allows the monitoring of
failures remotely from a reliable data communication in a mobile application
for Android operating system (OS) on a wireless network IEEE 802.11. As a
result, a prototype of the test bench for the Embedded System is presented in
which the main parameters of temperature sensors and operating conditions of
the dehumidifiers are checked.
