use:
Light brightness detection, light brightness sensor, has directionability, only sensor in front of the sensor in front of the sensor, which is better for light search effect
Module characteristics:
1 You can detect the brightness and light intensity of the surrounding environment (compared with the light resistance, the direction is better, you can perceive the light source in the fixed direction)
2 The sensitivity can be adjusted (the blue digital potentiometer is adjusted in the figure)
3 Working voltage 3.3V-5V
4 Output form: Do digital switch output (0 and 1) and AO analog voltage output
5 There is a fixed bolt hole for easy installation
6 small board PCB size: 3.2cm * 1.4cm
Instruction
1 The optical diode module is the most sensitive to the environmental light. It is generally used to detect the brightness and light of the surrounding environment. In most occasions, it can be commonly used in the light -sensitive resistance sensor module.Fixed light source.
2 When the module does not reach the set threshold when the light -free conditions or the light strong, the DO port outputs high level. When the external environment is strong than the set threshold, the module D0 outputs low;
3 Small board digital output D0 can be directly connected to the single -chip microcomputer to detect the high and low levels by single -chip microcomputers, so as to detect the light change of the environment;
4 Small board digital output DO can directly drive the shop's relay module, which can form a photoelectric switch;

5 Small board analog output AO can be connected to the AD module of our store. Through AD conversion, you can obtain a more accurate value of environmental light strong
