• 1 photosensitive resistance module’s most sensitive to ambient light, commonly used to detect environment around the
• brightness of the light, or MCU trigger relay module, etc.;
• 2 module in the environment light intensity than set threshold, output high level DO end, when the environment light
• intensity more than set threshold, the DO output low level;
• 3 the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low
• level, thus to detect the environment light intensity change;
• 4 the DO output can be directly driven our relay module, which can form a light-operated switch.

• 1 Using photosensitive resistance sensor sensitive type;
• 2 Working Voltage:3.5V-5V;
• 3 Output form:Digital Switch show (0 and 1);
• 4 Fixed Bolt Hole,easy installation;
• 5 Small PCB size:3.2CM*1.7CM;
• 6 the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma;
• 7 with adjustable potentiometer to adjust light brightness;
