With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.

PROJECT DESCRIPTION

The main intention of this project is to detect a telephone ring in noisy environments and provide a visual indication by a flasher to the user for easy identification of incoming calls. This system is quite useful in some places wherein hearing telephone ring is difficult; for instance, workshops and factories.

 The phone line is connected to the circuit. This circuit is developed using an opto-isolator and an electromechanical relay to switch on/off the lamp driven by a transistor. This concept can be extended in future and implemented in the real-time scenarios.

Q & A
Q:  Where is it used?
A:  It is used at shopping mall, theaters, hotels, where automatic door opening is required
Q:  What is incoming phone ring light flasher?
A:  It gives a visual indication whenever the phone rings.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q:  What to do when the lamp fails and what is the maximum lamp rating that can be used?
A:  If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.
