Detail Description:
Description:
A simple photosensitive resistance sensor LM393 based module with LDR. The LM393 is a comparator IC, and the LDR is an analog sensor. When the LDR is used with the LM393, it will generate a digital output that will go HIGH if the light is detected above the pre-determined threshold which is set by the potentiometer located on the module. There is also an analog output varies between 0V and 5V depending on the amount of light.
Use:
Light brightness detection, light brightness sensor, smart car light-seeking module
Module features:
1. Using sensitive photosensitive resistance sensor
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
3. Equipped with adjustable potentiometer to adjust the brightness of detection light
4. Working voltage 3.3V-5V
5. Output form: digital switch output (0 and 1)
6. With fixing bolt holes for easy installation
7. Small board PCB size: 3.2cm x 1.4cm
8. Use wide voltage LM393 comparator
Module instructions
1. The photoresistor module is the most sensitive to ambient light, and is generally used to detect the brightness of the ambient light, trigger the single-chip microcomputer or relay module, etc.,
2. When the module's ambient light brightness does not reach the set threshold, the DO terminal outputs a high level, when the ambient light brightness exceeds the set threshold, the DO terminal outputs a low level,
3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the change of the light brightness of the environment,
4. The DO output terminal can directly drive our relay module, which can form a light control switch.
