Most of the electrical circuits or electrical devices are affected by the atmospherics temperature. The main cause of atmospheric temperature such as failure of insulation short circuited and also decreases the efficiency of electrical circuits or devices. Day by day this problem can increase. In order to overcome this problem of temperature level, an electric circuit has been designed. There are some components which are used in for designing of the electrical circuits. Such components are : Temperature Sensor , Arduino microcontroller , , MATLAB Simulation , Inverter, rectifier , auto transformer , step down transformer which is connected to the load . The main aim that connected an temperature sensor with Arduino Microcontroller and interface with simulation and verify the result in the hardware implementation.
