Extensive experience in design and programming of microcontrollers with different types of sensors. I am dedicated to the technology for more than 20 years, in the design of circuits and development of applications in several languages, and technology.
The project will be based on an Arduino Nano, a buzzer, and a non-invasive current sensor, it will sense the current and calculate the power factor, according to the defined threshold the buzzer will sound.
The customer must define the threshold of the power factor to activate the buzzer (default <0.75), additionally inform the voltage and maximum current to calculate the power factor.
