Photo-sensitive ( Photo sensitive ) sensor module ( LDR ) is the most sensitive for the environmental light intensity and it is generally used for detecting the ambient brightness and intensity of the environment. Without light intensity it will not reach the threshold resulting for low level output but, when the external environment light intensity exceeds the set threshold it will result for a high level output.

The output is directly connected with the microcontroller, for the microcontroller to detect the light level, thereby to detect environmental intensity change. Small digital output can directly drive the relay module, which can be composed of a photoelectric switch.

Specifications:

  • Input Voltage: 3.3V-5V
  • Output: Digital Switching form
  • Main chip: LM393 Photosensitive sensor
  • Output can be directly connected to the microcontroller I/O port.
  • The sensitivity of the signal detection can be adjusted.
  • Reserve a line voltage to compare circuit.
  • PCB size: 30mm x 15mm.
