5516 Optical Sensitive Resistance Light Detection Photosensitive Sensor Module Board DIY KitFeature:1. Using Sensitive Photoresistor Sensor.2. Comparator output, with clean signal, good waveform, strong driving ability, more than 15 mA.3. With potentiometer regulating temperature detection threshold.4. Fixed bolt hole for easy installation.5. Using a Wide Voltage LM393 Comparator.6. Usage: Luminance detection, Luminance sensor, Intelligent car light seeking module.Specification:Working voltage 3.3V-5VOutput Form: Digital Switch Output (0 and 1)PCB Size of Small Plate: 32mm*14mm*5mm/1.25*0.55*0.19''Packing weight: 2gOperation Manual:1. Photoresistor module is the most sensitive to environmental light. It is generally used to detect the brightness of the surrounding light, trigger single-chip computer or relay module, etc.2. When the ambient light brightness does not reach the set threshold, the DO output high level. When the ambient light brightness exceeds the set threshold, the DO output low level.3. DO output terminal can be directly connected with the single-chip computer, through the single-chip computer to detect high and low levels, thereby detecting changes in the brightness of the environment4. The DO output terminal can directly drive the relay module, thus forming a light-controlled switch.Wiring instructions:1. VCC Connecting to power supply positive 3.3-5V2. GND Connecting to Negative Electrode of Power Supply3. DO TTL Switching Signal OutputNote: Please allow 1-3cm differs due to manual measurement.Due to the different display and different light, the picture may not show the actual color of the item.
