 A Simple Light Control Switch using LM311

 FM Radio Kit by Nina Gajjar

 

A Simple Light Control Switch

LSW-0814

This is a simple LM311 Comparator based switch which can be used for various purposes:

1.  With an LDR as a sensor, it may be used as a  DAY or Night Switch.
2.  You may use any other resistive sensor to activate or deactivate relay for your own purpose

Designed on a Single sided board, my purpose to make this project was to switch ON  many staircase lights that we have. I have to put them OFF  every day in the Morning and switch OFF every evenings!!

Kit is supplied with choice of two size of LDRs. This was found important as, in my case, I had to place LDR a little bit away from the Light-Switch PCB. If you wish to use a transparent plastic case to house this project, you may use Large LDR for direct mounting to PCB.
