LM393 Photosensitive Light-Dependent Control Sensor Module with LDR

The LM393 Photosensitive Light-Dependent Control Sensor LDR Module is designed to detect the intensity of light using a Light Dependent Resistor (LDR). Here are the key features and specifications of this module:

  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

  Specifications:  

• Operating Voltage: 3.3V to 5V
• Operating Current: 15mA
• Length: 32mm
• Width: 14mm
• Height: 8mm
• Weight: 3g

  How it works:  

• The LDR module detects ambient light intensity using the Light Dependent Resistor (LDR).
• When the light intensity exceeds a set threshold, the DO port outputs high, otherwise, it outputs low.
• The digital output (DO) can be connected directly to an MCU to detect changes in ambient light intensity.
• The digital output can also drive a relay module to create a photoelectric switch.
• The analog output (AO) can be connected to an ADC to get a more accurate light intensity value.

  Pins:  

• VCC: 3.3V to 5V DC
• GND: Ground
• DO: Digital Output
• AO: Analog Output

  Package Includes:  

• 1 x LM393 Photosensitive Light-Dependent Control Sensor LDR Module
