Light - Color Sensor
The Digital LDR Module is used to detect the presence of light / measuring the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of signal detection can be adjusted using the potentiometer.
Use it to detect the light brightness in your environment and decide to switch OFF or ON light? Or maybe to adjust the brightness of the LED of your house?
You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it.
It comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection. The module comes with a power LED and a status LED as an indicator.
LDR Module Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.
How it Works :
1. 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;
2. Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;
3. Digital output module DO can directly drive the relay module, which can be composed of a photoelectric switch.
Pin Details :
VCC ↔ 3.3V to 5V DC.
GND ↔ Ground.
DO ↔ Digital Output.
Features :
- LM393 based design.
- It can detect ambient brightness and light intensity.
- Adjustable sensitivity (via blue digital potentiometer adjustment).
- Output Digital – 0V to 5V, Adjustable trigger level from preset.
- LEDs indicating output and power.
Package Includes :
- 1 x Digital LDR Module
This LM393 Photosensitive Light-Dependent Control Sensor LDR Module is using a high-quality LM393 voltage comparator. Easy to install using the sensitive type photosensitive resistance sensor the comparator output signal gives a clean and good waveform.
Driving ability is 15mA with the adjustable potentiometer, it can adjust the brightness of the light. Working voltage is 3. 3V to 5v. Where output is a digital switch output. Since this module is sensitive to the light, usually used for detecting the ambient brightness and light intensity.
You can use this board digital output DO port drive relay module directly(our store on sale these relay modules), and can also use as a photoelectric switch. The analog output ao connects with ad module and it can get more precise light intensity value through the ad-converter.
