Lm393 Light Sensor Module Raspberry Pi

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.

Lm393 light sensor module raspberry pi.

Vcc gnd digital analog. In the following example we will use the analog output to measure light level. Lm393 light sensor module 3 3 5v input light sensor for arduino raspberry pi brand. Connect the module to the raspberry pi.

We can only use digital output directly on raspberry pi because raspberry pi doesn t come with any analog input pin. This light sensor module has 4 wires. The digital output has a trim potentiometer that can be used to set a trigger light level. The brightness of surrounding environment and the light intensity can be detected compare with the photoresistor directivity is relatively good can perceive the fixed direction of the light source 2 sensitivity adjustable the blue digital potentiometer adjustment figure 3.

With fixed bolt hole for easy. Make sure this fits by entering your model number. Only 7 left in stock order soon. Lm393 light sensor module 3 3 5v input light sensor for arduino raspberry pi top obtain the spe.

This fits your. 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. The lm393 is a simple photo resistor light sensor that has both analog and digital outputs. Digital switching outputs 0 and 1 5.

Lm393 light sensor module 3 3 5v input light sensor for arduino raspberry pi 1 offer from 7 00. The digital pin is the digital output while the analog pin is the analog output. If you re new to python i recommend taking a quick crash course on the basics of python. 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. 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.
