Working voltage of 3.3V - 5V
Output form: Digital switching output (0 and 1)
With fixed bolt hole, convenient installation
Small circuit board prints: 3.2 cm x 1.4 cm
The use of wide voltage comparator LM393
with potentiometer adjustable tests adjustable brightness of the light
1.Photosensitive resistance module has the most sensitive ambient light, generally used for detecting environment immediate of the brightness of the module light, trigger SMC or relay, etc.;
2 brightness of ambient light module can not reach the threshold of setting, DO exit end of high-level, when light brightness of the external environment of the development of threshold, only to stop output low level;
3 output port can be directly connects to the single-chip minicomputer, through the single-chip minicomputer for detecting level up and down, so the change in intensity of the light of the test environment;
4 end of output can directly drive the relay module, which can form a light switch - operated.
1 VCC positive power 3.3 - 5V supply
2 GND power is negative
3 exit switching TTL signal DO
1 x Module
Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3 cm.
