Overview
The LDR light Module detects the embient light, it includes a high precision comparator (LM393) and a adjustable potentionmeter to make design in simple way.
A light sensor (LDR or Light Dependent Resistor) is a simple component that provides a variable resistance that changes with light.
Features
- Operating voltage : DC +3.3V/5V
- Onboard power status LED.
- Onboard sensor status LED.
Pin Definition
AO
Analog output, real-time output voltage signal on the sensor's resistance.
VCC
Power input, DC +3.3V/5V.
DO
Sensor detection output (Logic 'H'/'L'). The threshold adjustable via potentiometer.
