Temperature control on an industrial device

Abstract

That have been my engineering second year project in ENSIM. That is a predictive and preventive maintenance system of wind turbines. It operates wireless and works with an analogue temperature sensors AD590.

Presentation

The general objective is to inform of the temperature evolution of an industrial device. A sensor gives a temperature information. A fist microcontroler send this data by a Zigbee specification, a wireless communication protocol. The data can be read in direct direct flow with a specific software which work on RS232 protocol (USB). Moreover, all the data are published on the internet by a specific API. The communication is made with ethernet and TCP/IP. An email is sent when the temperature is over a threshold.

Specifics devices & cost

Mbed development

It is the easier part of this project. TMP102 is an I2C temperature sensor. TMP102 is available in SOT.

I have developed a DIP package on eagle.
