Photo-Resistor Sensor (LDR or Photo-cell) capacitive proximity sensor WiFi / Bluetooth connectivityThis is a very small light sensor . It is called light sensor or photocell or LDR (light dependent sensor) or photo resistor. A photocell changes resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something). Features Light resistance : ~1k Ohm Dark resistance : ~10k Ohm Max voltage : 150V Max power: 100mW Dimensions 2 x 4 x 5mm 4mm between pins 31mm
