This article presents an air conditioning monitoring system for small
ISP, performing periodic readings of certain sensors, collecting information that
defines full operation such as temperature, electrical current, flame sensor and
an IR emitter which will allow control of the air conditioner per application.
Currently the local provider market Brazil is growing, and many do not have
some kind of monitoring system. In this article we used the MQTT protocol, the
Raspberrypi, Esp8266, DHT22 hardware, we also used a simple MQTT dashboard
for viewing the collected data.
