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
