Hello sir,

My project is control the light in an room depending on the light intensity for which i am using the PIR sensor and LDR resistor..

my question is that the LDR output ll be analog how to interface the bulb to that using and MSP430 launch pad kit.coz we need to set some reference value to LDR o/p i.e even after detecting the human in the room by sensor it should not turn on the light if intensity doesnot falls below the set reference value by us.
pls reply back as soon as possible.

Thanks & Regards
Amar Poojari
