So, in this Arduino interfacing tutorial series let’s look at such a sensor module built around the TSL25911 light sensor. TSL25911 Ambient Light Sensor Module This is a high-sensitivity digital ...

LDR (Light-Dependent Resistor) Module or, photoresistor, is a type of resistor where resitant value change with intensity of light. This module has 4 pin: VCC GND DO (Digital) AO (Analog) Digital ...

Light sensor Dark sensor Light and dark detection using an LDR For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using ...

This file is for an arduino light sensor that uses an arduino photoresistor to measure light values and based on that certain actions are made. Some actions incleda a buzzer (if there is too much ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

Our schematic consists on 3 elements which are: Photoresistor (LDR), Piezo Buzzer, 1 – 10 kΩ. The LDR can be connected any way you want because doesn’t have polarity. For resistance you can use from 1 ...

The other end of the resistor is connected to ground. A wire is connected to the junction of the resistor and photoresistor and connected to analog input 1 on the Arduino. As the sunlight received by ...
