About the item

The LM393 LDR Sensor Module detects the presence of light or measures the intensity of light. In presence of light, the output goes high and it becomes low in the absence of light. A potentiometer can be used to adjust the sensitivity of the signal detection..
ing Hole Screw | Easy to install | Signal output indicator light | Able to detect ambient brightness and light intensity | Adjustable sensitivity.
LxWxH : 14 x 8 x 4 mm.
As the LM393 module is sensitive to light, it is usually used for detecting the ambient brightness and light intensity..
Operating voltage : 3.3V - 5V Power indicator : Red Digital switch output indicator : Green Output : DO digital switch output (0 and 1), AO analog voltage output.

LDR Light Dependent Sensor Module is used to detect the intensity of light. When there is light, the resistance of LDR will become low according to the intensity of light. The greater the intensity of light, the lower the resistance of LDR. The sensor has a potentiometer knob that can be adjusted to change the sensitivity of LDR towards light.With such a wide variation in resistance, LDRs are easy to use. Features : LM393 based design Can detect ambient brightness and light intensity Adjustable sensitivity (via blue digital potentiometer adjustment) Output Digital 0V to 5V, Adjustable trigger level from preset Output Analog 0V to 5V based on light falling on the LDR LEDs indicating output and power How it works: Light detecting resistor(LDR) module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity. Module light conditions or light intensity reach the set threshold, DO port output high when the external ambient light intensity exceeds a set threshold, the module D0 output low; Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes; Digital output module DO can directly drive the relay module, which can be composed of a photoelectric switch; Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value Pins: VCC = 3.3V to 5V DC GND = Ground DO = Digital Output AO = Analog Output Packaging Included: 2x LM393 LDR MODULE
