0.0 / 5 0

1965

Characteristics

1 using photosensitive sensor resistance sensitive type;

2 Operating voltage: 3.5 V, 5 V;

3 output form: digital switching show (0 and 1);

4 fixed screw hole, easy installation;

5 small PCB Size: 3.2 cm * 1.7 cm;

6 the comparator output, the clean signal, good wave, driving ability is strong, for more than 15 mA;

7 with adjustable potentiometer to adjust the brightness of the light;

Instructions

1 Photosensitive strength modulus most sensitive to ambient light, commonly used to detect environment around thebrightness light, or MCU module trip relay, etc .;

2 module in ambient light intensity than the limit set, the high-level end DO output, when the ambient light intensity over the set limit, the low level output;

3 the output can be connected directly to the microcontroller through single chip microcomputer for detecting the high and low level thereby to detect the ambient light intensity changes;

4 the output can be directly carried our relay module, which can form a light-operated switch.

Application

Test the brightness of the surrounding environment.
