Light Sensor (LDR module) Photosensitive resistance Module
Description
Photosensitive resistance module Is most sensitive to ambient light. Module is commonly used to detect amient light. Module can be directly connected with Microcontrollers or to trigger relay module. Module sets output to LOW logic (on DO pin) if the light intensity is higher than set point. Module only supports digital output and does not has Analog output.
Features
- Uses photosensitive resistance sensor
- Uses LM393 wide voltage comparator
- Clean signal, good waveform, strong driving ability for more than 15 mA
- With adjustable potentiometer to adjust light sensitivity
- Has single mounting hole
- Small board PCB size: 3.2 cm x 1.4 cm
Technical Specifications
- Operating voltage of 3.3 V to 5 V
- Output Type: Digital Output (0 and 1)
- PCB size: 3.2 cm x 1.4 cm
- Output Low: when light intensity is higher than set point
- Output High: when light intensity is lower than set point
