High Sensitivity Ldr Photoresistor Light Sensor Module For Arduino Diy Projects - 5Pcs!

In the vast landscape of electronic components, the humble photoresistor stands out as a versatile tool for sensing and measuring light. Often referred to as a light-dependent resistor (LDR), the photoresistor is a device that changes its electrical resistance in response to light intensity. This unique characteristic makes it indispensable in a wide range of applications, from simple DIY projects to sophisticated industrial and scientific setups. What is a Photoresistor? At its core, a photoresistor is a type of resistor that has a variable resistance based on the amount of light it receives. It works on the principle that as the intensity of light increases, the resistance of the material decreases. This change in resistance can be easily measured and used to trigger various actions or to control circuits. How Does a Photoresistor Work? Photoresistors are typically made from materials such as cadmium sulfide (CdS), copper oxide (CuO), or tin oxide (SnO2). When light falls on the surface of the photoresistor, it excites the electrons in the material, allowing more current to flow through it. The more light, the lower the resistance; conversely, less light means higher resistance. This relationship between light and resistance forms the foundation of photoresistors.

I asked for them on April 27, 2023, and they arrived today June 15 in Mexico🇲🇽. Shipping was moderate, full 20 pcs received. Put on two leds and two different resistors (resistance and LDR), the blue LED is with a resistance of 47 kohms while the green LED has the LDR connected. How is seen in the images if they work because when receiving light the resistance low and allows more current and voltage, while applying shadow to the LDR the resistance increases and therefore limits the flow of electrons and therefore also decreases the voltage. All functional. I recommend buying👍🏻💯
