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 digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. Commonly available ...
The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
The LDR (Light Dependent Resistor) sensor changes resistance based on the light intensity. In this project, the LDR is connected to an Arduino Uno to automatically control lighting. When light ...
We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...
In addition, smart street lights will control power more effectively by reducing the risk of the automated street light system warming as well as the risk of incidents. Wasting energy by keeping the ...
