  Internet of Things (IoT) is the new industrial slogan for connecting
intelligent and unintelligent devices to the web. The problem of security of
data transfer, interoperability of different proposed methodologies, the
ubiquity of Wi-Fi and the development of low power consuming MCUs has broadened
the search for the best alternative technology for IoT in the oil and gas
sector. This paper focus on the communication method for IoT devices to
determine the level of functionality and the efficiency of interfacing the new
MOD-WIFI-ESP8266-DEV Wi-Fi unit based on the IEEE 802.11 standard with MSP430
by Texas Instrument. The system controls LEDs and monitors Temperature/Humidity
sensor (DHT11) using Android application and web service. The system presents
in three-layered structure an ecosystem of lightweight, small size, reduced
cost and low power IoT system. It is expected that industries/users of this
system would be able to control, monitor, and analyse data generated by the web
of connected devices.
