LM393 LDR OPTICAL SENSITIVE RESISTANCE MODULE LIGHT

LM393 LDR OPTICAL SENSITIVE RESISTANCE MODULE LIGHT

LM393 LDR OPTICAL SENSITIVE RESISTANCE MODULE LIGHT, Smart car module Using the sensitive type photosensitive resistance sensor Waveform of the comparator output signal is good, strong driving ability With adjustable potentiometer can adjust and detect the brightness of the light Come with bolt holes for easy installation

Module features:

• 1 photosensitive resistance module’s most sensitive to ambient light, commonly used to detect the environment around the
• brightness of the light, or MCU trigger relay module, etc.;
• 2 modules in the environment light intensity than the set threshold, output high level DO end, when the environment light
• intensity more than the set threshold, the DO output is low level;
• 3 the DO output can be directly connected to the microcontroller, through single-chip microcomputer to detect the 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.

Features:
