This article demonstrates real-time training, detection and recognition of a human face with OpenCV using the Eigenface Sign in to add this video to a playlist. Switch S1 is used to enable or disable the buzzer and LED in the circuit. I made a very simple version of this project today. See the schematic circuit. Recommended for you.
This power failure alarm project is a power supply monitoring device that will trigger a buzzer when the mains supply cuts off. This device is helpful to inform the loss of power supply to some critical installation such as a pump in a fish tank. Make sure that the coil of the.
This minuscule power failure alarm circuit is a power supply monitoring device is the system on/off switch, and LED2 (5mm Red) is an optional visual indicator.
Fuse cum Power Failure Indicator Detailed Circuit Diagram Available
The idea of making this Power cut/on indicator came because of a real time problem faced in DIC (Design Innovation Centre) department of Vigyan Ashram,.
The whole setup must be insulated properly for safety reasons. Sign in to add this video to a playlist.
The final installation is done as shown in the figure below: The left side of the DC adaptor is Mains supply connected and it provides a input signal for arduino and supply for relay. Leave a Reply Cancel reply. When power supply goes off due to power cut or fuse blown off, no light falls on LDR1 and the output of transistor T2 goes low.

The entire circuit of fuse and power failure indicator is build and fabricated around LDR, timer IC and LED. Here LED get power-supply from AC source which is. CIRCUIT DESCRIPITION a) Power Supply b) Mains Failure Detector c) NOT and several fixed output voltages, making it useful in a wide range of applications.
The base of transistor T2 is connected to the collector of T1.
