Dark and Light Activated Relay circuit diagram


Posted on Feb 5, 2014

The potensiometer adjust the trigger on` level. The diode in the circuit diagram shows to be 1N914. This is ok if you have a light-duty relay, also the 1N914 is a signal diode so actually does not qualify. Use a 1N4001 (or better) instead. A couple of substitutes for the 2N2222 transistor are: NTE123A, ECG123A, PN100, etc. We aim to transmit more
