6pcs Digital Light Intensity Sensor Module - 3 Pin Photo Resistor Photoresistor Board with DO Output for Arduino - Light Detection Switch, Photosensitive Sensor for DIY Projects, Robotics, and Smart Home Automation

Module Features : Can detect the brightness and the ambient light intensity (compared with photo-resistor, this module has better directionality , can sense light in fixed direction)Adjustable sensitivity (use the blue digital potentiometer to adjust)Operating Voltage: 3.3V-5VOutput Format : DO digital switching outputs (0 and 1) Has a fixed bolt holes for easy installationPCB Size : About 3.2cm * 1.4cm Module Instructions: Photodiode module is most sensitive to environmental light intensity , generally used for detecting the ambient brightness and light intensity , can be common with photosensitive resistance sensor module in most cases , the difference between this two is that Photodiode module has a better directionality, can sense light in fixed direction;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 directly drive the relay module, which can form a light-controlled switch. Product Wiring Instructions: VCC to Power "+" ，GND to Power "-" ，DO to TTL Signal Output ，Switch signal output A sensitive sensor type photoresistorThe comparator output signal is clean, good waveform, driving ability, more than 15mA.Adjustable potentiometer to adjust the brightness of the light detectionUsing a wide voltage LM393 comparatorVCC can be directly connected with 5V microcontroller.VCC can be directly connected with 3.3V microcontroller. Detection brightness can be adjusted: Turn the potentiometer clockwise to detect the increase in brightnessTurn the potentiometer counterclockwise to detect the decrease in brightness Application: Light intensity detection, intelligent car light module, with directional, only sense light source in front of the sensor, better to use for searching light. Detection brightness can be adjusted: Turn the potentiometer clockwise to detect the increase in brightnessTurn the potentiometer counterclockwise to detect the decrease in brightness Application: Light intensity detection, intelligent car light module, with directional, only sense light source in front of the sensor, better to use for searching light. The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
