Main aim of this paper control the home automation system by sending SMS
through GSM Modem. The user can be access the remotely and providing security when the
user is away from the place. The automation systems are becoming very important role in
the today world.GSM signal covers all over the world widely. So by using GSM band we can
control the home appliances efficiently with very low cost by short message services. If any
of the sensors goes beyond the set threshold value, then the microcontroller recognizes it
and sends particular message to the house owner. For this purpose, we are using GSM
modem (SIM900A). The house owner number was initially stored in the system. So, any
abnormal condition occurs in house, then the owner immediately receive an alert message
from the GSM modem interfaced to the LPC 2148 microcontroller.
