Lm393 Light Sensor Module Raspberry Pi
The biggest problem we face with this circuit is the fact that the pi doesn t have any analogue pins.
Lm393 light sensor module raspberry pi. The digital output has a trim potentiometer that can be used to set a trigger light level. Vcc gnd digital analog. The light sensor code. The lm393 is a simple photo resistor light sensor that has both analog and digital outputs.
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. This fits your. With fixed bolt hole for easy. In the following example we will use the analog output to measure light level.
Digital switching outputs 0 and 1 5. 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. Light level detection the brightness of the light sensor is directional only inductive sensor in front of the light source used to find light better. Lm393 light sensor module 3 3 5v input light sensor for arduino raspberry pi brand.
We can only use digital output directly on raspberry pi because raspberry pi doesn t come with any analog input pin. Running the program to use the light meter load and run the program 08 light meter py in mu. If you re new to python i recommend taking a quick crash course on the basics of python. This light sensor module has 4 wires.
The digital pin is the digital output while the analog pin is the analog output. Only 7 left in stock order soon. The code for this project is pretty simple and will tell us roughly whether it is light shady or completely dark. Connect the module to the raspberry pi.
