Description:

1. The photosensitive resistance module's most sensitive to ambient light, generally used to detect the environment around the brightness of the light, or MCU trigger relay module, etc.;
2. Module in the environment light intensity short of setting threshold, output high level DO end, when the environment light intensity more than set threshold, output DO low level;
3. The DO output can be attached directly to the single chip microcomputer, 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 our relay module, which can form a light-operated switch.
5. Small plate analog output AO and AD module, through the AD conversion, can obtain more accurate values of environmental light;

Features: 

1. The sensitive type photosensitive resistance sensor
2. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
3. With adjustable potentiometer can detect light brightness adjustment
4. The working voltage of 3.3 V to 5 V
5. The output form: DO digital switch output (0 and 1) and AO analog voltage output
6. Has a fixed bolt hole, convenient installation
7. Small board PCB size: 3.2 cm x 1.4 cm
8. Using the LM393 wide voltage comparator
