LDR (Light Dependant Resistor). Dark resistance >20M Ohm, light <80 Ohm. The two outer pins connect to the LDR. A fixed 10 K ohm resistor connected between the middle pin and the ‘S’ pin is included on the module. This simplifies the building of a measurement bridge circuit.
Size: 41 * 15 * 12.5mmThe main chip: LM393, vibration probesOperating voltage: DC 3-5V
Photo interupter module use the buildin arduino led. If the sensor is broken the LED is turned on. Device senses a signal, LED lights, otherwise off.
