Photosensitive Module Light Sensor 3 Pin with LDR
Light sensor module with adjustable sensitivity through the trimmer.
When the brightness exceeds the set threshold, the digital output DO goes to high logic level (+ VCC).
It can be powered and used with both 3.3V and 5V logic.
It uses the integrated LM393 as a comparator that guarantees particular operational stability.
It has two LEDs. One detects power and the other represents the digital output
The photoresist is welded to the module, but it is possible to remove it and connect it externally through two wires.
VCC: 3.3V or 5V power supply
GND: mass (0V)
DO: digital output
The card has a hole for fixing it.
Dimensions: 32x14mm (excluding pin size and photoresistance)
