LM393 Light Sensor Module

BD 7.500

This light sensor module is ideal for circuits which are equipped with a microcontroller platform like Ardunio. Through this module, a twilight switch for example can be implemented, which performs a defined action with corresponding brightness. The sensitivity / switching threshold can be adjusted via a potentiometer. Of course, the light sensor can also be used for other applications. A fast cabling is guaranteed by the four included Dupont cables. There are no limits to creativity.

Photodiode module is most sensitive to the ambient light, generally used to detect the brightness of the ambient light intensity, photoresistor sensor module Universal In most cases, the difference between the two is that photodiode module directional, can sense the fixed the direction of the light source.

Module in the light conditions or the light intensity of less than a set threshold, DO port outputs a high level, when the external environment when the light intensity exceeds the set threshold value, the module D0 output is low.
The small board digital output D0 can be connected directly with the microcontroller microcontroller to detect high and low to detect environmental light intensity change.
Small board digital output DO OUR relay module can directly drive, which can be composed of a photoelectric switch.

Product Details

Module Features:
1. The brightness of the environment and the intensity of lighting can be detected (compared with the photoresistor, the directivity is relatively good, it can perceive the fixed direction of the source of the lamp)
2. The sensitivity is adjusted by the blue digital adjustment of the potentiometer (Fig.)
3. Operating voltage 3.3V-5V
4. Digital switching outputs (0 and 1)
5. With fixed bolt hole for easy installation
6. Small PCB size: 3.2 cm * 1.4 cm / 1.25 "* 0.55"
Instructions for use:
1. The photodiode module is most sensitive to the surrounding lamp, it is usually used to detect the brightness of the intensity of the surrounding lamp, the photoconductor sensor module is universal in most cases, the difference between them is that the photodiode module is directed, it can sense a fixed direction of the light source
2. The module in conditions when the lamp or the intensity is less than the set threshold, makes the port reach a high level, when the external environment, when the lamp intensity exceeds the set threshold, the output of the D0 module is low
3. A small digital output board D0 can be connected directly to the microcontroller of the microcontroller to detect high and low, to detect changes in the ambient light intensity
4. Small digital output board makes our relay module can directly control, which can be composed of a photoelectric switch
