In the kit industrial boiler temperature industrial parameter monitoring is very important. In the earlier days it was done manually but that was dangerous and difficult for person in units like furnace boilers etc. With the rise of revolution in electronics the friendly and automatic system has been designed that provide solution to this with minimum error and better efficiency.
In the kit industrial boiler temperature the circuit is based on AVR ATMEGA168 micro controller and different temperature sensors are there as a slave devices. Here the master device is microcontroller. At a regular time interval the master keeps on initiating all the sensors and reads their values.
In the kit industrial boiler temperature read temperature is displayed on the LCD. As the temperature of any location exceeds some predefined threshold temperature, the alarm system is generated and heating element is turned off of that location via relay driving unit. We have used four different sensor networks. The controllers also send the data to PC to be logged via the USB to UART interfacing. The user can set the temperature threshold on the basis of which the temperature will be regulated.
