Overview of this 3 pin ldr Sensor module

Introducing roboway 3 pin ldr Sensor module at the best price in India with Roboway. This sensor module uses an LDR (Light Dependent Resistor) to detect the surrounding light level. This sensor gives  automatically senses brightness for example it increases or decreases output based on how much light is present. Brighter light decreases resistance, and dim light increases it.

It comes with an onboard potentiometer to fine-tune light sensitivity according to your needs and also it is fits easily into various setups and requires minimal space. This sensor give digital output and it can output a signal that changes with light intensity, or a HIGH/LOW signal when light crosses a certain threshold.

Features:-

Light-sensitive – It detects changes in ambient light using an LDR (Light Dependent Resistor).

3-pin connection – Includes VCC, GND, and OUT for easy connection to microcontrollers.

Adjustable sensitivity – Some versions have a built-in potentiometer to fine-tune light detection.

Digital output – Sensor gives a HIGH or LOW signal based on light intensity.

Works in various lighting conditions – Reliable in both indoor and outdoor environments.

Long life – Solid-state design with no moving parts, making it durable.

Pin outs:-

  • External 3.3V-5V VCC
  • External GND GND
  • DO digital output interface, a small plate (0 and 1)
  • AO small board analog output interface

How to use:-

  • Photosensitive resistor module most sensitive to environmental light intensity is generally use 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
