Phicon Bc547 transistor and ldr Sensor, 10 Pic 5mm Ldr & 10 Pic Bc 547 NPN Transistors Electronic Components Electronic Hobby Kit

LDRs are tiny light-sensing devices also known as photoresistors. An LDR is a resistor whose resistance changes as the amount of light falling on it changes. The resistance of the LDR decreases with an increase in light intensity. This property allows us to use them for making light sensing circuits. LDR Sensor photoresistor best suitable for school science projects and also for multipurpose uses
