IOT based Home Automation with Fault Monitoring

Energy consumption and power-saving have become most prominent now a day. In-home appliances, continuous use of load power in more amounts, and due to heating of the load (switching, vibrations, temperature changes, etc.), the load failure rate increases. In this approach, recent technologies came into interest, such as GSM/IOT use for the loads switching via mobile application or internet to turn the load off when they are not in use, also providing the mechanism to monitor various parameters like temperature, Vibrations of the load to predict early failure of the load also providing the mechanism to turn off the load. These devices become significant expenditures because the user is unwilling to risk external damage that disrupts the system's proper operation. This work developed the Simulink model that contains a single-phase AC voltage regulator for controlling the speed of load (fan). Different sensors values compare with reference values in MATLAB programming to monitor the fault and cut the load. In hardware model of the system contains an Atmega328 microcontroller, sensors such as temperature, vibration, current sensors, etc., Triac, load, NodeMCU, crystal display, GSM sim, etc. All are connected wire /wirelessly to control the speed, and also IoT paradigm is applied to the devices through node MCU to cut the load. Monitor the specific parameter and receive the SMS through GSM sim on mobile if a fault occurs. The suggested sensor and monitoring software solution allows the system to be integrated into the Cloud. These details will be necessary for product support and maintenance and customer assistance. Controlling of home power devices using programming by using a mobile app, i.e., on /off the device when not required form outstation also diagnosis the devices to detect initial failure so avoid more damage to appliances.
