The purpose of this project is to alert the remote user regarding fuse status in a critical electrical equipment and alert if it got fused out. The display of fuse status is sent to the user mobile through Bluetooth. This consists of two electrically isolated power sensors for sensing the presence of electrical power. One of the power sensors is connected before the fuse to be monitored and the other after the fuse. The power status from these sensors is fed to a microcontroller. Microcontroller continuously monitors the status of these two sensors. If the power status of second sensor is low and the first sensor is high, then the microcontroller identifies this as a break in fuse circuit and sends an appropriate message to the user mobile via Bluetooth. If both the sensors output goes low then microcontroller identifies this as power supply failure and sends the appropriate message to the Bluetooth application. Once the data is available with mobile, we can use this data to send e-mail to the concern personal about the fault.        

The objectives of the project include:  

1. Real-time fuse monitoring.
2. Alarming in fuse blown situations.
3. Sending the status of the fuse to the user mobile via Bluetooth.
