Tiivistelmä
In the Nordic winter, a car users need to warm their cars in order to start up the frozen engine of the car. Usually, it takes around 5 minutes for him/her to wait outside for warming the frozen engine. Thus, car users suffer a lot to warm their cars in the cold environment. To deal with this issue, a remote control system was designed in this thesis to remotely turn on/off the heater of the car by sending an SMS. The whole process of the thesis project lasted two months, and it was conducted in the Technobothnia laboratory. The remote control system is an application based on a GSM modem, serial communication, and MCU technology. The GSM modem was used to transmit and receive SMSs between the system and the user’s phone through a GSM network. MCU was used for switching the heater through a relay, and it was also used for receiving the detected temperature through a digital thermometer. As a result, in the system test phase, the remote control system could successfully remotely control a lamp by sending an SMS, and the actual temperature could be reported through the SMS. However, the power of the heater limited the usage of the remote control heater; and the security risk would be another main issue in the future. In conclusion, the initial objectives of the thesis project were achieved, and the whole process run well according to the project plan.
