![]() The signal from the flip-flop is fed to a dual input Class AB pull-push amplifier to produce an alternating output with the same waveform but with a higher power enough to power up any equipment in the power rating of the system. The traditional square wave derived from a stable multi-vibrator would be substituted for modified sine wave oscillator which would be designed by the combination of a timer and a flip-flop. This project would increase the knowledge on power inverter application by constructing a 12V DC to 220V AC with output power rating at 600VA with frequency varying between 49.95Hz, which is approximately 50 Hz. The 600VA DC-AC power inverter is designed to produce backup power that runs on 12V DC batteries which are ecofriendly to produce backup power for a longer period of time. ![]() This makes it quite unaffordable by people with low income. The cost of maintenance turns to be expensive since they run on fuel, compared to an Inverter. The carbon mono-oxide and the black oil from the generator pose threats to the environment as air and soil or water pollutant making it non-environmentally friendly. Some of the limitations of using generator as alternative or additional source of electricity are mostly noisy during its operation, which causes disturbances in the neighborhood. Even though all these backup supply systems turn to perform their said functions to some extent, they turn to pose some challenges. The most common backup supply systems available on the market are Automotive Generator Sets (convert mechanical energy to electrical energy by means of burning fossil fuel) and UPS (Uninterrupted power supply). The overall system was tested andfound perfectly functional.ĪBSTRACT In the light of prevailing power cuts in the country, there is a sudden rise of a need to come up with backup power solutions. The general operation of the system and performance is dependent on the temperature difference between the preset temperature value and external temperature intended to be monitored. The results of the tests showed that the power output of the circuit is switched OFF hence switching OFF the heating device or an alarm is triggered ON when the device exceeded a preset temperature level. ![]() ![]() The system is powered using a 12V power supply. Basically the system is constructed using temperature sensors and comparators. The methodology involves the application of linear precision temperature sensors i.e., they generate a voltage that is directly proportional to the temperature. The power output of the circuit is cut off or switched OFF or an alarm is triggered ON if the temperature of the external input is equal to or, greater than the preset temperature value. The circuit works by monitoring temperature from an external input and comparing the temperature level with that of a preset temperature value. This research focuses on the design and construction of a Dual Sensor heat-monitoring system. Convenience and safeguarding our home appliances have become an important issue when dealing with an advancement and growth of an economy. ![]()
