Description
- photosensitive resistance module’s most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc.;
- module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level;
- the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change;
the DO output can be directly driven our relay module, which can form a light-operated switch.
- Product:LDR Module LM393
- Features:
- Using a wide voltage LM393 comparator
- With a mouting screw hole, easy to install
- Using the sensitive type photosensitive resistance sensor
- The comparator output signal clean waveform is good, driving ability, than 15mA
- 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
- Arduino Compatible
