Description: Using a wide voltage LM393 comparator? the comparator output signal clean waveform is good, driving ability, than 15mA Using the sensitive type photosensitive resistance sensor With adjustable potentiometer can adjust the brightness of the light detected Working voltage: 3.3V-5V Output: DO digital switch output (0 and 1), AO analog voltage output With a mouting screw hole, easy to install PCB Size: 32 x 14mm Specification: - 1. Photoresistor module is the most sensitive to ambient light, so generally used to detect brightness of ambient light, trigger or relay modules, and microcontroller. - 2. When light brightness of ambient is less than the set threshold, DO-side output is high, when light brightness of ambient is over the threshold, DO-ended output is low. - 3. DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, to detect changes of environment in light intensity. - 4. DO outputs can directly drive the shop relay module, which can form a light control switch. Package Includes: 1 Piece Photosensitive Sensor Module
