About this item

• •Features:
• •1. A sensitive sensor type photoresistor
• •2. The comparator output signal is clean, good waveform, driving ability, more than 15mA.
• •3. Adjustable potentiometer to adjust the brightness of the light detection
• •4. Working voltage: 3.3V-5V
• •5. Output format: digital switching outputs (0 and 1)
• •6. A fixed bolt holes for easy installation
• •7. PCB size: 3.2cm x 1.4cm
• •8. Wide voltage LM393 comparator
• •Module for use:
• •1. Photosensitive resistor module most sensitive to ambient light, generally used to detect the brightness of ambient light, triggering microcontroller or relay modules;
• •2. The module when the brightness of ambient light can not reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO end output low;
• •3. DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light to change;
• •4. DO output of the relay module can directly drive the shop, which can be composed of a light control switch.
• •Include:
• •3x DollaTek Light sensor
