12PCS Photosensitive Sensor Module Digital Light Intensity Detection for Ar-duino Electronic Practice DIY
Specifications: Photosensitive Resistance Sensor Module features: 1.Working voltage 3.3V-5V 2.Pin Header: 3Pin 3.Output Format:DO digital switching outputs (0 and 1) and AO analog voltage output. 4.Has a fixed bolt holes for easy installation. 5.Adjustable sensitivity (use the blue digital potentiometer to adjust) . 6.Can detect the brightness and the ambient light intensity (compared with photo-resistor, this module has better directionality, can sense light in fixed direction) . 7.Comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA. 8.Using a wide voltage LM393 comparator. Wiring Instructions: VCC: Connect to power supply positive 3.3-5V GND: Connect to power supply negative DO: TTL switch signal output Module instructions: 1.The photoresistor module is most sensitive to ambient light, generally used to detect the brightness of the surrounding environment, triggering a single-chip or relay module; 2. When the brightness of the ambient light reaches the set threshold, the DO end outputs a high level. When the ambient light brightness exceeds the set threshold, the DO end outputs a low level; 3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high-low level is detected by the single-chip microcomputer, thereby detecting the change of the light brightness of the environment; 4. The DO output terminal can directly drive the relay module of the store, which can form a light control switch. 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. Package including: 12 x Photosensi
