Electricity is crucial for critical sectors such as banking, healthcare,
education, and business. However, in developing nations like Cameroon,
persistent power fluctuations and outages present significant challenges,
leading to communication disruptions, food spoilage, water supply
interruptions, and financial losses. This study proposes a novel solution: a
three-input automatic transfer switch integrated with Internet of Things (IoT)
and data logging capabilities. The system automatically switches between three
independent power sources based on priority and availability, employing
electromechanical contactors, relays, and timers for seamless switching. It
incorporates ATMEGA328P microcontrollers, a GSM module for communication, and
an SD card module for efficient data logging. Safety measures, such as
miniature circuit breakers, voltage monitoring relays, and proper grounding,
ensure user protection and system integrity. A user-friendly mobile application
enables remote manual switching and real-time system information requests,
while SMS notifications inform consumers about power source changes. The system
has a power rating of 4.752kW, accommodating a maximum continuous load of the
same value. Voltage dividers provide a reliable 3.37VDC
output from a 12VDC input, and data logging operates effectively by
storing system data onto an SD card every 1.5 seconds. Comprehensive testing
validates the system’s performance, with an average percentage error of 2.31%
compared to actual values, falling within an acceptable range. This solution
distinguishes itself by incorporating modern technologies like data logging and
IoT, addressing the limitations of existing alternatives.
