Product description：

• The photodiode module is the most sensitive to the ambient light intensity. It is generally used to detect the brightness and light intensity of the surrounding environment. It can be used with the photoresistor sensor module in most situations. The difference between the two is that the photodiode module has good directivity and can sense fixed Direction of the light source.
  

• The sensor module has strong adaptability to ambient light. It uses a photodiode sensor for ambient light detection. When the module has no ambient light or the brightness does not reach the set threshold, the DO terminal outputs a high level. When the ambient ambient light brightness exceeds the set When the threshold is set, the DO terminal outputs a low level and the working voltage is 3.3V-5V. The brightness of this sensor can be adjusted by a potentiometer. The photoresistor module is the most sensitive to ambient light. It is generally used to detect the brightness of the ambient light and trigger a microcontroller or a relay module. The DO output can directly drive our relay module, which can form a light-controlled switch.

Product performance：

• When the ambient light is no light or the brightness does not reach the set threshold, the DO terminal outputs Output, high level, when the ambient ambient light brightness exceeds the set threshold, DO Output low. Detection brightness can be adjusted by potentiometer, clockwise Adjust the potentiometer with the needle to detect the brightness increase; Adjust the potentiometer counterclockwise to detect the brightness cut back.

• Comparator output, clean signal, good waveform, strong driving ability, exceeding 15mA.

• The sensor module output port OUT can be directly connected to the microcontroller IO port.Yes, you can also directly drive a 5V relay; connection method: VCC-VCC; GND-GND; OUT-IO

• The module can be powered by 3.3V-5V DC power supply. When the power is turned on When the red power indicator is on;
