Photosensitive Resistance Sensor Module – LM393

Description:

A simple photosensitive resistance sensor LM393 based module with LDR. The LM393 is a comparator IC, and the LDR is an analog sensor. When the LDR is used with the LM393, it will generate a digital output that will go HIGH if the light is detected above the pre-determined threshold which is set by the potentiometer located on the module. There is also an analog output varies between 0V and 5V depending on the amount of light.

 

Specifications:

• Operating voltage: 3.3V – 5V
• Output: D0 digital switch output (0 and 1), A0 analog output
• Potentiometer for setting the light threshold
• Dimensions: 32mm x 14mm
