Amp -Photosensitive Sensor Highlights Generic Brand Photosensitive Sensor Description: Using the sensitive type photosensitive resistance sensor. The comparator output, clean signal, good waveform, driving ability is strong, for more than 15MA. The working voltage from 3.3V to 5V, The output form: digital switching output (0 and 1). With adjustable potentiometer can adjust and detect light brightness. It is of good directivity and can detect fixed direction light. With bolt holes for easy installation. Module Instructions 1. The most sensitive ambient light photosensitive resistor module, generally used to detect the environment around the light brightness, or MCU trigger relay module, etc.; 2. Module in the environment light intensity below the set threshold, DO end high level output, when the environment light intensity over set threshold, DO low level output; 3. The output of DO can be attached to the single-chip microcomputer directly, through a single-chip microcomputer to detect high and low level, thus to detect the environment light intensity change; 4. The DO output can be directly driven by our relay module, which can form a light-operated switch. Specification: Size: 48 x 16 x 8 mm / 1.9 x 0.6 x 0.3 inch Package includes: 1 Piece Photosensitive Sensor Module
