The use of Generator has become a very common in almost every passive infrastructure companies, Industries, hospitals, Townships etc, while by using these Generators, a number of challenges are faced by the users and companies. Among all other challenges fuel stealing from the generator fuel tank has become an alarming issue as the price of the fuel is touching sky high day by day. Although many security and safety features are added but the fuel robbery is still out of control and the loss of the companies are immeasurable. So an advanced control system is designed with the PIC microcontroller which can measure the level of fuel in the fuel tank by using a high tech ultrasound sensor and store the data in to a data acquisition system.

Cellular communication becomes the major mode of communication in present century. With the development of this phase of communication the globalization process is also in its peak of speed. The development of cellular communication is largely depending on the improvement and stability of Base Transceiver Station (BTS) room. So for the purpose of the development of cellular communication a large numbered BTS rooms are installed throughout the world. To ensure proper support from BTS rooms there must be a security system to avoid any unnecessary vulnerability. Therefore multiple alarm system is designed to secure the BTS rooms from any undesired circumstances. This system is designed with a PIC Microcontroller as a main controller and a several sensors are interfaced with it to provide high temperature alarm, smoke alarm, door alarm and water alarm. All these alarms are interfaced with the alarm box in the BTS room which provides the current status directly to Network Management Centre (NMC) of a Global System for Mobile (GSM) communication network.
