The digital output has a trim potentiometer that can be used to set a trigger light level.
Lm393 light sensor module raspberry pi.
The lm393 is a simple photo resistor light sensor that has both analog and digital outputs.
Digital switching outputs 0 and 1 5.
With fixed bolt hole for easy.
Connect breadboard to raspberry pi using figure 3 as a reference connect the gpio pins on raspberry pi to the breadboard using three female to male jumper wires.
The digital pin is the digital output while the analog pin is the analog output.

Make sure this fits by entering your model number.
Running the program to use the light meter load and run the program 08 light meter py in mu.
The biggest problem we face with this circuit is the fact that the pi doesn t have any analogue pins.
Lm393 digital light sensor module 4 pin this light sensor module combines both the ky 018and 3 pin design of lm393 to create a universal module that can act as a digital switch if connected to do pin or as an analog sensor if connected to ao analog output.
In the following example we will use the analog output to measure light level.
If you re new to python i recommend taking a quick crash course on the basics of python.
