Applications
- Remote System Monitoring: In a remote system monitoring application, a Microcontroller for example could be used to constantly monitor the status of a remote sensors, let say temperature or moisture sensors. If a certain condition is reached, the program will send an SMS to notify the situation, if these sensors are installed in a farm for example, the farmer could be notified of any situation happening in the farm about heat, moisture, drought, etc.

- Security Access Control: A security access can be implemented at apartments or housing complexes. A security guard could inform by intercom a resident if he/she has a visitor at the main gate. with a replied SMS, the resident could open remotely the gate for his/her visitor.
- Vehicle tracking: A GSM/GPRS module together with a GPS module can be used to create a real time vehicle tracking device. An SMS could also be sent to notify that the car has entered a restricted area, notify about the level of remaining fuel in the car etc. If the vehicle is stolen not only the system can indicate the location of the vehicle but an SMS could also be sent to switch OFF the engine.
- SMS Gateway: To send and receive SMS for advertisements.
- Pre-paid Electricity: The customer can recharge pre-paid electricity by sending an SMS with a recharge coupon to a pre-paid electricity recharge server.
