-		This function executes as a part of cron job . It monitors the condition of the SBHS devices. 
-		To be specific it does the following checks :

-			2.It checks the status of fan ,heater, sensor on SBHS by performing a series of variations on them and analysing 
-				the result
-		At the end it updates the Boards database with the device status.
-		It mails the admin if any fault occurs.The mail comprises of machine Id of faulty board and probable cause.
