Abstarct: According to the increasing need of industrial societies for automation and saving time and costs, also increasing accuracy and efficiency of industrial parts and machineries, noticing the way of monitoring and more appropriate and easier access to monitoring systems have turned to one of the most important engineering arguments. In recent years mobile communication technology was increasingly expanded and this provided the condition for establishment of fast mobile networks for transmitting data. Also monitoring remote machine operations with the least error and without presence of men is highly significant. One of the methods for remote monitoring in electronic systems is using GSM modems and monitoring through text message. Among dominant mobile technologies, GSM is the most popular mobile technology. This enables subscribers to use their mobile phones in most areas of the world. Given to level of iniquitousness of the technology across the globe it is significant to design and produce remote monitoring devices by means of GSM systems and remote monitoring by means of high frequency circuits in all fields. In this thesis we reviewed designing and producing monitoring and controlling system through GSM network, sending and receiving information through short message in order to supervise, make order and monitor remote equipment. The main part of the device includes microcontroller model Atmega 32 along with communication parts called GSM which is known as Sim900 with working frequency of 850 to 900 Megahertz and it is the main processor of the device, with one temperature sensor (Lm35), two electromagnetic relay, one LCD along with PCB and all parts and feeding part.
