Specification:Product Name:PhotoresistorMaterials:Metal, Electric PartsWeight:4gLDR Head Dia:5mmMaximum Voltage: 150 Volt DCMaximum Wattage: 100mWOperating Temperature: -30 ~ +70 deg CSpectral Peak: 540nmModel:5528Light Resistance (10 Lux): 8-20 KohmDark Resistance: 1 Mohm100?10: 0.8Response time: 20ms (Rise), 30ms (Down)Package Content:5Pcs x PhotoresistorDescriptions:Light-dependent resistors or photoresistors are a staple of electronics. If you need a way to sense the level of ambient light then there is no easier way to do it. As the light on the sensor increases then the resistance across the two leads decreases. If you have a rear view mirror that darkens when its hit buy headlights you can check in the little hole on face of the mirror and you will see those wavy lines of photoresistor!
