Modul cảm biến ánh sáng AO/DO

Use:
light intensity detection, light level sensors, smart car search optical module
module Features:
1, using sensitive type photosensitive resistance sensor
2, the comparator output signal clean, good waveform, driving ability, more than 15mA.
3, with adjustable potentiometer detects the light intensity can be adjusted
4, the working voltage 3.3V-5V
5, the output form: DO digital switching outputs (0 and 1) and AO analog voltage output
6, a fixed bolt hole for easy installation
7, small PCB board size: 3.2 cm x 1.4cm
8, using a wide voltage LM393 comparator
module for use
1, photoresistor module most sensitive to ambient light, generally used to detect the brightness of ambient light, triggers microcontroller or relay module and so on;
2, when the ambient light level modules reach the set threshold, DO-side output high, when the ambient light level exceeds the threshold, DO terminal output low;
3, with the output of the microcontroller DO directly connected, through the microcontroller to detect high and low, thereby detecting the light intensity changes in the environment;
4, DO outputs can directly drive the shop relay module, which can form a light control switch.

5, small plates analog output AO and AD modules can be connected through AD conversion, you can get a more accurate ambient light intensity values;
