This paper describes a network prototype of embedded wireless system with a thermocouple sensor to monitor the temperature variation in industrial operations through internet. The hardware and software selection and the sensor interfacing have been described. Using Raspberry Pi and internet service, the temperature at a remote location is continuously tracked and thus it provides a truthful and convenient mode of control. Thermocouple sensor senses the temperature variation and information is transmitted via internet to the control room. Internet based sensing and process monitoring is said to hold the key for the factories of future. © 2020 IJSTR.
