LDR Sensor Module

LDR Sensor Module

This light sensor module or light dependent resistor module (LDR Module) uses the GL5528 photo-resistor to detect the light intensity of the environment. The resistance of the sensor decreases when the light intensity of the environment increases. The LM393 op-amp is configured as a "voltage follower" to increase the accuracy of this device.


·        Operating voltage: 3.3 to 5Vdc.

·        Operating current: 10mA with 5V.

·        Light resistance (at 10 LUX): 8: 2 K

·        Status LED indicator.

·        Adjustable trigger threshold. Adjust potentiometer clockwise to increase sensitivity.                

·        Digital and analog output.

·        Analog output can be connected to microcontroller analog pin to get light intensity value.

·        Rising Response Time:  20ms

·        Peak Wavelength:  540nm.

·        PCB Size (LXWXH):32.5x1.6x36mm

·        Weight: 6g.

Application Examples

·        You can make a light turn on when it is getting dark.

·        With a laser pointer you can make a cheap intruder alarm.

·        Tracking of solar panels to the sun direction for best solar power generation efficiency.
