ITEM NAME:Four Wires Light Detection Photosensitive Sensor Module Photodiode With Dir M2J9 Four Wires Light Detection Photosensitive Sensor Module Photodiode With Dir M2J9 With adjustable potentiometer can adjust the light intensity detected. Application:Detecting light intensity, light intensity sensor, with directional, only sense light source in front of the sensor, better to use for searching light. 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-5V Output Format : DO digital switching outputs (0 and 1) and AO analog voltage output Has a fixed bolt holes for easy installation Module Instructions: 1.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; 2. 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; 3.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; 4. Analog output and the AD conversion process, can achieve higher accuracy. colour:blue Material:plastic size:PCB Size : 3.2cm * 1.4cm Package Contents: 1 * Sensor Module.Application:Detecting light intensity, light intensity sensor, with directional, only sense light source in front of the sensor, better to use for searching light.
