WEBSERVER I hope this basic tutorial helps you in making your project. PLC Programming So therefore it is not visible to the naked eye and a photodiode which is also called a light-dependent resistor has a very high resistance in the absence of light and the resistance of the photodiode drops when light falls on it as the name itself indicate the resistance of the photodiode depends on the intensity of light falling on it. In order to find time, we will use the logic that the first IR sensor will detect whether there is some vehicle is present in front of the sensor or not. Breadboard. Both IR sensors are provided with the necessary power supply connection.
