Supply voltage: DC 3.3-5V ; Output : Digital signal 0&1; Adopt sensitive photoresistor sensor, Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of the ambient light and trigger the microcontroller or relay module, etc.Equipped with adjustable potentiometer to adjust the brightness of the detected light.
With power indicator (red) and relay pull-in indicator (blue), and four M3 screw mounting holes for easy installation.
When ambient light intensity does not reach the threshold value, the module DO port output high; when the ambient light intensity exceeds a set threshold, the D0 output low;Digital outputs D0 can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting the light intensity changes in the environment.
The DO output terminal can be directly connected to the microcontroller, and the microcontroller is used to detect high and low levels to detect changes in ambient light brightness; The DO output terminal can directly drive the relay module, thereby forming a light-controlled switch.The analog output AO of the small board can be connected to the AD module. Through AD conversion, a more accurate value of the ambient light intensity can be obtained.
