Detecting light intensity, light intensity sensors, optical module smart car hunt
1, the use of sensitive photoresistor type sensor
2, the comparator output signals clean, good waveform, driving ability, than 15mA.
3 with adjustable potentiometer to adjust the brightness of the light detected
4, the working voltage of 3.3V-5V
5, the output form: DO digital switching output 0 and 1 And AO analog voltage output
6, a fixed bolt hole for easy installation
7, small PCB board size: 3.2cm x 1.4cm
8, using a wide voltage comparator LM393
1, ambient light module photoresistor most sensitive, generally used to detect the brightness of ambient light, single-chip trigger or relay module;
2, the module when the ambient light brightness of less than the threshold value, DO-side output high, when the ambient light level exceeds the set threshold, DO terminal output low;
3, DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light changes;
4, DO output of the relay module can directly drive the shop, which can be composed of a light control switch.
5, Small plate AO analog output module can be connected to AD through AD conversion, you can get a more accurate ambient light intensity value;
